- Avoid directly translating as 'фамильярность', which carries a stronger, predominantly negative connotation of inappropriate informality. The English word is broader and more neutral.
- Do not confuse with 'familiar' as a noun (meaning a spirit or close attendant), which is archaic.
Common Mistakes
- Using 'familiarity' as a countable noun (e.g., 'I have many familiarities with...' – INCORRECT). It is primarily uncountable.
- Misspelling as 'familiarty' or 'familiaraty'.
