~たら (conditional)
grammar160 sentences
The conditional/temporal ~たら, attaching to past-form predicates and meaning 'if/when X happens/happened.' Covers both 'if X' (hypothetical) and 'when X' (real, completed) — context picks the reading. With completed past events: '(once) X happened, (then) Y.' More versatile than ~ば, usable for specific one-time conditions, sequential 'when X, then Y,' the temporal-discovery 'when I X-ed, I found Y.'
