ikisiyle

Ikisiyle is a Turkish adverbial phrase formed from the numeral iki (two) plus the suffix -si and the instrumental suffix -yle, yielding ikisiyle. It literally means “with the two of them” or “with both,” and is used to indicate accompaniment or means involving two subjects or items. The form can function as a complement to a verb or as part of a larger clause, signaling that two specific entities participate in the action.

In usage, ikisiyle is commonly employed to refer to two previously mentioned people or items. For example, "İkisiyle konuştum" means “I talked with both of them,” and "İkisiyle çalıştılar" can be rendered as “They worked with both of them” or “They worked together with both.” The expression can also appear with the particle de for emphasis, as in "İkisiyle de anlaştık." In formal or careful prose, speakers may opt for alternatives such as iki kişiyle or iki kişiyle birlikte, but ikisiyle remains widely understood in everyday Turkish.

Etymologically, ikisiyle reflects Turkish word-building patterns that fuse a numeral with possessive and instrumental suffixes to denote collective accompaniment. The phrase is versatile but can carry slightly informal tonal weight; in highly formal writing, more explicit constructions are often preferred.
