～たなりWhile... ~ing, Remaining, Not or ever since, Keep or leave

When following the た, past-tense form of a verb, the conjunction particle なり 'shape' indicates something existing in an ongoing state, similar to まま. This may be translated as 'while (A)', or 'remaining (A)'.

Due to ～たなり sentences usually describing something happening while in the state of (A), it will often be followed directly by a comma, or by the conjunctive form of the auxiliary verb だ, で. After this, the (B) phrase will then describe what is happening during (A).

～たなり will primarily be used to express an undesirable state continuing despite (A) having happened, although this is not a strict rule.

As ～たなり indicates that (A) is something that is continuing to stay in the same state, it will often have the nuance of 'ever since (A)' in situations where a significant amount of time has passed.

Caution

This なり derives from the noun 形(なり) 'shape' in its hiragana form, and is different to the なり that is used as the classic copula.
