concomitantemente

Concomitantemente is a formal adverb in Portuguese (also found in Italian with the same meaning) used to indicate that two or more events, conditions, or processes occur at the same time or in parallel. It corresponds to the English terms concurrently or simultaneously, but in Portuguese it often carries a nuance of a linked or interacting co-occurrence. In everyday language, the synonym simultaneamente is more common, while concomitantemente tends to appear in technical, scientific, or legal writing.

Etymology and usage notes: the word derives from the adjective concomitante, meaning accompanying, itself from Latin concomitans (accompanying) or a related form, built from con- (with) and comitari (to accompany). The adverb is formed by adding the suffix -mente to the adjective. Concomitantemente is used to emphasize that phenomena happen together and may be related or interdependent. It can modify verbs or clauses and is often paired with phrases such as "concomitantemente com" to specify the co-occurring reference.

Examples: "Os sintomas surgiram concomitantemente." "Os efeitos adversos ocorreram concomitantemente com o uso do medicamento." "A pesquisa analisou fatores econômicos e sociais concomitantemente." Its use is most common in formal or technical prose, where precise description of parallel occurrence is required.
