⚠️ False Friends & Tricky Words

13 exercise sets — 40+ common mistakes. The vocabulary traps that trip up even advanced non-native English speakers in IT.

What is a false friend? A word in English that looks or sounds like a word in your native language — but means something completely different. These cause confident-sounding errors: your grammar is correct, your vocabulary is wrong, and the meaning is lost.

Classic false friends in IT English

⚠️ "actual"
❌ Wrong use "The actual version is 3.2."
✅ Correct English "The current version is 3.2."

"Actual" means "real/genuine", not "current/latest". Languages like Ukrainian, Russian, Spanish, and German have a false cognate meaning "current".

⚠️ "implement"
❌ Wrong use "This function implements that the server is running."
✅ Correct English "This function checks / verifies that the server is running."

"Implement" means "to build / put into practice". It does not mean "imply" or "indicate".

⚠️ "library"
❌ Wrong use "I went to the library to read about algorithms."
✅ Correct English "I imported the library. / I visited the bookstore."

In IT, "library" = a reusable code package. Outside IT, "library" = a place to borrow books.

⚠️ "eventually"
❌ Wrong use "Eventually, this function returns the result synchronously."
✅ Correct English "Finally / Ultimately, this function returns…"

"Eventually" in English means "after a delay / at some unspecified point in the future". In many European languages the cognate means "possibly" or "perhaps".

🌐 False Friends by Native Language

Common traps depend on your native language. Here are the most frequent false-friend errors for three major language groups.

🇺🇦 Ukrainian & Russian speakers

  • ✗ “programist” → ✓ programmer — no “-ist” suffix in English
  • ✗ “realize” (реалізувати) → ✓ implement — English “realize” means to understand/notice
  • ✗ “actual” (актуальний) → ✓ current / up-to-date — English “actual” means real/genuine

🇪🇸 Spanish & Portuguese speakers

  • ✗ “actual” (= current) → ✓ current — English “actual” ≠ “current”
  • ✗ “sensible” (= sensato) → ✓ reasonable / smart — “sensible” ≠ “sensitive”
  • ✗ “eventually” (= posiblemente) → ✓ at some future point — always means “in the end”, not “perhaps”

🇩🇪 German speakers

  • ✗ “realize” (realisieren = umsetzen) → ✓ implement — English “realize” = to understand/notice
  • ✗ “control” (kontrollieren = prüfen) → ✓ check / verify — English “control” implies authority
  • ✗ “actual” (aktuell = current) → ✓ current / latest — English “actual” = real/genuine
