〜たら

About

ら can be attached to any past tense word ending in た to form the たら conditional form. ～たら is used for conditional "if" and "when" statements.

E.g. おいしかったら、何なんでも食たべれる。 "I can eat anything if it's tasty."

E.g. デザート食たべたら、帰かえりましょう。 "Once you eat dessert let's go home."

For nouns/な-adjectives, the 「(noun/な-adjective)だったら」 pattern can be used. じゃない・ではない are used for negatives.

E.g. 子供こどもだったら無理むり。 "It's impossible if it's a kid."

E.g. 子供こどもじゃなかったら無理むり。 "It's impossible if it's not a kid."

If a たら statement will be ambiguous (either "if" or "when") it is often paired with もし ("with") in order to clarify.

E.g. もし安やすくなったら、買かいます。 "If it gets cheaper, I'll buy it."
