My English is good enough that I can highlight it on my résumé. But I am not a native and it shows, especially when talking. Even when writing, it is not that idiosyncratic; idiotisms, phrasial verbs and plain vocabulary are (somewhat) frequent shortcomings.
I try to use international English, because I find id “classier”. Colour, grey.
Tricks for non-native:
- For translating a technical term, go to Wikipedia in your language, expect to have an entry for the term, then look on the left column for the English interwiki link (provided it exists).
- For translating a phrase, go to Wordreference.com. It is a gold mine.
