Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лакунарный' (which is a correct cognate but still highly technical). The English term is far less common than its Russian counterpart. It is not equivalent to 'лакуна' (gap) itself; it's the adjective derived from it.
Common Mistakes
- Using it as a noun to mean simply 'a gap' (that's 'lacuna').
- Using it in informal contexts.
- Mispronouncing it as /ˈlæk.jʊ.nər/.
