The phrase 'ซึ่งกันและกัน (sûeng gan láe gan)' in Thai language is mainly used to denote a mutual situation or reciprocal actions between two parties or individuals. It is similar to English terms 'each other' or 'one another'. It often follows verbs to reflect the reciprocity of the action from both sides involved. Despite its literal meaning which suggests an involvement of at least two parties, it can be used when more than two parties are involved.
