TL;DR

Want to find a linguistics topic you could actually research? These 40 ideas cover everything from how languages change and how sounds are produced to bilingualism, language and identity, and the use of AI in language. Each one gives you a starting point for a research question, along with the tools or data you could use to explore it. If you want to build one into a full paper with one-on-one guidance from a PhD mentor, you can apply to the Lumiere Research Scholar Program.

If you’re interested in language and want to try a research project, this guide can help you get started. It covers 40 linguistics research ideas for high school students, ranging from language and dialects to pronunciation, communication, and language change. You can explore different areas of linguistics and choose an idea that you’d like to investigate further. If you are new to the process, our guide on how to write a research paper in high school is a good place to begin.

What does linguistics research look like for a high school student?

Linguistics research can start with a question you have probably already thought about. Why do some words mean different things depending on how they are used? Why do you and your friends talk one way online and another way in class? You can take questions like these and explore them by looking at conversations, social media posts, survey responses, recordings, or dictionary entries.

You do not need a lab to do linguistics research. What matters more is having a clear question, finding useful examples, and looking closely at what they tell you. Even a small project can be a good one if you have a focused question and enough evidence to support your answer.

How do you pick a linguistics topic you can finish?

Start with the part of language you find most interesting, then shrink it. Check three things before you commit: can you get enough examples, can you analyze them with tools you already have, and can you finish in a few months?

If you are still deciding, our post on how to choose a research mentor and area walks through the process step by step. A topic you can finish will always beat a topic that sounds impressive but stalls halfway.

Which linguistics topics need no special equipment?

Many of the ideas below only require public texts, free tools, or conversations with people you know, so the table groups them by what you’ll need to get started.

How do you keep linguistics research ethical?

If you record people, survey classmates, or study children's speech, ask for permission first and explain what you will use their words for. Keep names out of your paper, and get a parent or guardian's consent when your participants are under 18.

Research ideas in linguistics for high school students

Historical linguistics

Historical linguistics looks at how languages change over centuries, including lost sounds, borrowed words, and ancient languages.

1. Language shift and endangerment in Indigenous communities

Choose one community and one time period, list the factors your sources name, and count which ones come up most often. Stick to published sources unless you have clear permission to contact community members.

Research question: Which social, political, and historical factors led one Indigenous community to use its language less over time?

Tools and data needed: Published linguistic surveys, census or government language data, and university or community language archives.

Who is it right for? Students interested in history, culture, and how society shapes language.

2. Proto-language reconstruction

Start with a short list of basic words, such as numbers or family terms, line them up across the languages, and note which sounds correspond.

Research question: What can shared words across two or three related languages tell us about how their common ancestor sounded?

Tools and data needed: Dictionaries or open word databases, a spreadsheet, and an IPA (phonetic alphabet) chart.

Who is it right for? Students who enjoy puzzles and spotting patterns.

3. Sound changes across one language's history

Pick one sound, such as a particular vowel, and compare how the same set of words was spelled and pronounced in each period.

Research question: How did one sound change between the older and modern forms of a single language?

Tools and data needed: Historical texts, dictionaries that show older spellings, an IPA chart, and recordings of modern speakers.

Who is it right for? Students who like close detail and old texts.

4. Grammar changes in historical texts

Choose one grammar feature, such as word order in questions, and count how often each form appears in samples from two periods.

Research question: How did sentence structure in one language change between an older text and a modern one?

Tools and data needed: Free digital libraries such as Project Gutenberg and a spreadsheet for tallying.

Quick answers before you pick a linguistics topic

1. Can slang and internet language count as serious linguistics research?

Yes. Slang follows real patterns in word building, meaning, and social use, which is why it shows up in both morphology and sociolinguistics. A project works best when you collect real examples and explain the pattern you find rather than just listing words.

2. Can you research historical linguistics without knowing an ancient language?

Yes. Many topics in this area use published texts, dictionaries, and existing reconstructions, so you can work with translations and focus on the pattern of change. Pick a language family or time period with plenty of published material.

3. Can you combine two areas of linguistics in one project?

Yes. Ideas often overlap, for example, bilingual processing with emotion, or slang with online identity. Keep one area as the main focus and use the second as a lens so the project stays narrow enough to finish.

4. Do you need a mentor to do linguistics research?

It depends. You can start alone with public texts or a short survey, but a mentor helps you shape the question, choose a method, and check your analysis. If you want that kind of guidance through a full paper, you can apply to the Lumiere Research Scholar Program.
