Why English Vocabulary Challenges International Students
According to the British Council’s 2023 International Student Survey, 78% of non-native English speakers cite vocabulary as their biggest linguistic challenge when studying abroad. This isn’t surprising when you consider that the average native English speaker actively uses between 20,000-35,000 words, while a university-level international student typically commands 8,000-12,000 English words.
The University of Oxford Department of Education reports that understanding academic vocabulary specifically can impact a student’s overall academic performance by up to 30%. For international students, mastering Difficult Words in English isn’t just about communication—it’s directly linked to academic success.
Common Categories of Difficult Words in English
1. Homophones: Words That Sound Alike
Homophones are words that sound identical but have different meanings and spellings. These frequently cause confusion even among native speakers.
Examples:

- They’re: Contraction of “they are” (They’re studying for exams)

Strategies for Mastering Difficult English Words
1. Context-Based Learning
Research from the University of Cambridge suggests that learning words in context improves retention by 42% compared to memorizing isolated definitions. Instead of studying word lists, read academic articles in your field and note unfamiliar words as they appear naturally.
2. Etymology Awareness
Understanding word origins can help you recognize patterns. Approximately 60% of English vocabulary comes from Latin and Greek roots. For example, knowing that “bio” means “life” helps you understand words like biology, biography, and biodiversity.
3. Spaced Repetition
According to a 2022 study from the University of Edinburgh, using spaced repetition techniques—reviewing words at increasing intervals—improves vocabulary retention by up to 75% compared to cramming.
4. Active Use
Oxford University research shows that students who actively use new vocabulary in writing and speaking retain 80% more words after three months compared to those who only read or hear the words.

FAQ
What are the most difficult words in English to pronounce?
The most challenging words for non-native speakers typically include “worcestershire,” “colonel,” “queue,” “anemone,” “isthmus,” “squirrel,” “sixth,” “phenomenon,” “entrepreneur,” and “specific.” These words contain unusual spelling-pronunciation relationships, silent letters, or sound combinations that don’t exist in many other languages.
Why are English words so difficult to spell?
English spelling is challenging because the language has absorbed vocabulary from many different languages (Latin, French, Greek, German, etc.), each with their own spelling conventions. Additionally, pronunciation has evolved over centuries while spelling often remained fixed, creating inconsistencies between how words are written and pronounced.
What is the difference between “affect” and “effect”?
“Affect” is typically used as a verb meaning to influence something (e.g., “Stress can affect your studies”). “Effect” is usually a noun meaning the result of something (e.g., “The effect of regular study is improved grades”). However, “effect” can sometimes be a verb meaning “to bring about” and “affect” can be a noun referring to emotional expression.
How can I improve my English vocabulary as an international student?
Improve your vocabulary by reading widely in your field of study, learning words in context rather than isolated lists, using spaced repetition techniques with flashcards, practicing new words in conversation and writing, joining language exchange groups, watching English media with subtitles, and using specialized vocabulary apps like Anki or Memrise.
What are homophones and why are they confusing?
Homophones are words that sound the same but have different meanings and often different spellings (e.g., “there/their/they’re,” “right/write,” “two/too/to”). They’re confusing because when you hear them spoken, you need context to determine which word is being used, and when writing, you must remember the correct spelling for each meaning.
How many words do I need to know to be fluent in English?
Most linguists agree that knowing 8,000-9,000 word families is sufficient for comfortable university-level fluency. Native English speakers typically use 20,000-35,000 words, but research shows that just 2,000-3,000 of the most common words cover about 80% of everyday English usage. Academic English requires knowledge of an additional specialized vocabulary.
What are the most commonly misused English words?
Commonly misused words include “literally” (incorrectly used for emphasis), “ironic” (confused with coincidental), “disinterested” (confused with uninterested), “fewer/less” (fewer for countable items, less for uncountable), “i.e./e.g.” (i.e. means “that is,” e.g. means “for example”), and “compliment/complement” (praise versus something that completes).
How can I remember the meaning of difficult academic words?
Remember academic vocabulary by breaking words into root parts (prefixes, roots, suffixes), creating personal associations or mental images, using the new words immediately in sentences relevant to your studies, creating flashcards with example sentences, teaching the words to others, and reviewing words at spaced intervals.
Why does English have so many silent letters?
English has many silent letters because spelling often preserves the word’s etymology (history/origin) rather than its current pronunciation. Many silent letters were once pronounced but became silent as pronunciation evolved over centuries. Other silent letters were added by scholars to reflect Latin or Greek origins (like the ‘p’ in psychology).
What’s the difference between British and American English vocabulary?
British and American English differ in hundreds of everyday words: “flat” (UK) vs. “apartment” (US), “lift” vs. “elevator,” “petrol” vs. “gas,” “holiday” vs. “vacation,” “rubbish” vs. “trash,” etc. Academic terminology can also differ, particularly in certain fields like medicine and law. Both versions are acceptable in academic writing, but consistency is important.
