Yes thank you for pointing that out English is not my first language but one of 8 depending how you count because some are dialects of others that I converse in and I have trouble sometime with contracted words and also what you call in English "homonyms." However things like engineering, science (biology, chemistry, electronics, physics) and other thinks like ignorance, bias or what you mistakenly call "placebo" are fairly easily understood in any language.
