Who gets left out when we use complex language?

Reading time: 6 min

Goal: Show how overly complex language can exclude different groups of people and highlight the importance of clear, inclusive communication to ensure everyone can understand and participate.

Language is one of the most powerful tools we have for connection, learning, and change. But when we use overly complex language—long sentences, jargon, technical terms, or academic vocabulary—we don’t always gain our purpose. Sometimes, we just make it harder for others to understand us. And when that happens, people get left out. The question we must ask is: who are they

People with Different Educational Backgrounds 

  • Not everyone has had the same opportunities when it comes to education. Some may have left school early, gone to under-resourced schools, or learned in a different system. 
  •  When we speak or write using high-level or technical language without explanation, we risk excluding those who don’t have that vocabulary—not because their lack of intelligence, but because the lack of content accessibility. 

Example: 

  • Some VET learners come from diverse backgrounds—some may have left school early, others may be returning to study after many years. Complex explanations or academic wording can feel overwhelming and disempowering. If learners can’t understand what’s being asked, they may disengage—not because they lack ability, but because the language has become a barrier. 
  • In cultural sites, not all visitors arrive with the same academic or cultural reference points. When exhibit labels, audio tours, or public programs rely on advanced vocabulary or assume prior knowledge, they can feel intimidating or inaccessible. We may unintentionally signal: “This isn’t for you.” But cultural experiences should welcome everyone. 

Families and Caregivers 

  • In education parent newsletters, school forms, and curriculum nights are filled with important information. But how often do we ask: is this easy to understand? Families may feel intimidated or disconnected when school communication uses technical education terms or unclear directions. Plain language helps build trust and partnership between school and home—something every child benefits from. 
  • At the hospital family members often act as advocates, interpreters, or caregivers—but they aren’t always trained for the role. Medical instructions can leave them unsure how to help. When we explain things clearly and compassionately, we support not just the patient, but their whole support system. 
  • At the cultural sites young visitors are naturally curious, but they need information that matches their level of understanding. Family-friendly language, storytelling, and interactive experiences are not just “extras”—they’re essential tools for lifelong engagement with arts and culture. If children grow up feeling that museums or libraries speak their language, they’ll keep coming back. 

People with Cognitive or Learning Differences 

  • People with dyslexia, ADHD, or other learning differences often find dense or complicated writing harder to follow.  
  • Complex language can make it difficult to stay focused, process meaning, or retain information.  
  • If we truly want to include everyone in conversations—especially those about policies, rights, or services—then our words need to be easier to understand. 

Example:  

  • In education: not all students process language the same way. Some have learning differences like dyslexia, ADHD, or auditory processing challenges. Others may simply need more time to understand abstract ideas. When instructions, assessments, or lessons rely heavily on complex language, there is a risk making students feel confused or left behind—not because they can’t learn, but because the way we’re delivering the content is a barrier. 
  • Many VET students are working hard to improve their language, literacy, or numeracy skills while also learning new trades or qualifications. When instructions, assessments, or workplace documentation are written in difficult or unclear language, we risk setting them up to fail. Using plain English and breaking down concepts step by step helps learners feel more confident and capable. 
  • In cultural sites visitors with learning differences, memory challenges, or intellectual disabilities may find dense text or abstract ideas difficult to follow. Accessible communication—including clear layout, simpler sentences, and sensory options—helps ensure they’re included in meaningful and dignified ways. 
  • Clarity in healthcare isn’t optional—it’s ethical. Every patient has the right to understand their condition, their choices, and their treatment. When our language is clear, we empower people to make informed decisions. We reduce the risk of harm. Using plain language is a sign of respect. 

Non-Native Language Speakers 

  • For people who are learning a new language, every unfamiliar word is a barrier. Complex grammar, idioms, or advanced vocabulary can create confusion or embarrassment.  
  • Many people may choose not to speak up or participate if they fear they won’t understand—or be understood. Clear language levels the playing field and helps everyone join in. 

Example: 

  • In education for multilingual learners, every sentence is a puzzle. When we use idioms, uncommon vocabulary, or culturally specific references without support, we make that puzzle harder. Simplifying language, using visuals, and checking for understanding we’re making the message more accessible. 
  • For multilingual patients, healthcare terms may not translate clearly—or at all. Even when an interpreter is present, complicated explanations, idioms, or rapid speech can cause misunderstandings. Taking time to speak clearly, check for understanding, and offer visual aids or translated materials can greatly increase trust and treatment success. 

Young People 

  • Children and teenagers are often left out of important conversations simply because we assume they can’t understand certain ideas. But often, the problem isn’t the idea—it’s how we explain it.  
  • Our youngest students are constantly learning new words and concepts. When we take the time to explain ideas in clear, simple language, we help them connect the dots faster. It’s not about avoiding complexity—it’s about building a strong foundation first. After all, clarity in early education often leads to confidence in later learning. 

Everyday Readers and Listeners 

  • Even adults who are fluent, educated, and capable can be overwhelmed by complicated language. After a long day of work or when facing stressful situations (like reading medical advice or legal documents), no one benefits from confusion.  
  • Clarity isn’t just helpful for those with special needs—it benefits everyone

Workplace Supervisors and Industry Partners 

  • VET is built on strong partnerships with industry, but not all employers are fluent in the language of training packages, units of competency, or assessment criteria.  
  • When communication between RTOs (Registered Training Organisation) and employers is overly formal or unclear, it can cause confusion about expectations.  
  • Clear, direct language strengthens these relationships and improves outcomes for learners. 

Community Members Who Don’t Yet Feel “At Home” in the Space 

  • Sometimes the barrier isn’t physical—it’s cultural or emotional. If our tone feels too formal or academic, it may reinforce a sense of exclusion.  
  • Using warm, inclusive, and understandable language is one way to say: You belong here, and this story includes you.
