ましてや
ましてや
adverb
much less; let alone; still more so
1.
much less; let alone; to say nothing of
Used to introduce a more extreme case after stating something already difficult or unlikely. Implies 'if X is already the case, then Y is even more so.' Often appears in negative sentences meaning 'let alone.'

Conjunctive adverb used to escalate an argument. The structure is typically: 'A is already X. ましてや B is even more X.' The first clause establishes a baseline that is already extreme, and ましてや introduces something even further along that scale. Slightly formal; common in written arguments, speeches, and logical reasoning.
USAGE PATTERN:
- [easier/lesser case] + already X。ましてや + [harder/greater case] + even more X
- Often paired with negative endings: ～はずがない, ～わけがない, ～無理だ
SIMILAR WORDS:
- まして: let alone — shorter form, slightly less emphatic
- なおさら: all the more — emphasizes the strengthened degree, less contrastive
- いわんや: needless to say — classical/literary equivalent, very formal
