usullerle

Usullerle is a Turkish adverbial expression formed from the noun usul, meaning "method" or "principle," combined with the instrumental suffix -le. The construction roughly means "by means of methods" or "with methods" and functions to indicate the manner or means by which an action is performed.

In Turkish, usullerle is used in formal, technical, or academic writing to describe an act carried out according to prescribed procedures or methodologies. It is not a standalone noun but a grammatical form that accompanies a verb, for example: veriler usullerle toplandı; bu çalışma usullerle gerçekleştirildi. The phrase can emphasize adherence to procedure rather than the content of the action and is commonly found in discussions of research design, evaluation, or standard operating procedures.

The base word usul appears in several related terms, such as usul fiqh (principles of Islamic jurisprudence) or bilim usulleri (methods of science). Usullerle contrasts with other expressions like yöntemlerle (with techniques) and can carry nuances about systematic, rule-based processes or formal methodological conditions in a given context.

As a term, usullerle does not denote a widely recognized organization, doctrine, or movement. Its primary function is grammatical: signaling that an action is performed in a method-based, procedural manner. In everyday language, speakers often prefer more common forms like yöntemlerle or usullere uygun olarak, depending on the context.
