This document discusses mixed conditional sentences, which contain elements of more than one conditional type. There are two types of mixed conditionals: 1) Present result of a past condition, which uses the past perfect tense in the if-clause and would/could/might in the main clause. 2) Past result of a present or continuing condition, which uses the past simple in the if-clause and would have/could have in the main clause. Examples are provided for each type of mixed conditional.
