When partnered with several of the 仮定(かてい) ‘assumption’ based expressions that are used in Japanese, the 格助詞(かくじょし) (case marking particle) と may be used to show a hypothesis about a certain result. This is one of the 結果(けっか) ‘result’ highlighting uses of と. Structures that may be seen are as follows:
(A) としたら (B) - When (A) is the result (B).
(A) とすれば (B) - If the result is (A), (B).
(A) とすると (B) - A result of (A) will be (B).
Although these nuances are slightly different, realistically they are used in almost exactly the same way, to express a possible (undetermined) result. This can be translated to ‘assuming that (A)’, or ‘if it were the case that (A)’.
To use these expressions, simply attach と and your chosen variation of したら to the end of any verb/い-Adjective, or noun/な-Adjective followed by .
