In Lojban, sarcasm is denoted with attitudinals such as je'unai, which marks the statement as a logical contradiction, and/or zo'o, to mark it as humour and/or ianai for disbelief. Certain kinds of ambiguity are quite plausible with Lojban, for example, unlike in English, you don't have to specify that a countable noun is singular or plural if you don't want to. You can, however, easily distinguish between ideas like 'the stereotypical rose is red', 'the majority of roses are red', or 'the roses we are discussing are red', which can get clumsy in English
