Injectées

Injectées is the feminine plural past participle of the French verb injecter. In French grammar, it functions as an adjective that agrees with a feminine plural noun, indicating that something has been introduced or administered by injection. It is commonly found in medical, pharmacological, and biological contexts, where substances or materials have been delivered through an injection. The masculine plural form is injectés and the feminine singular form is injectée.

In use, injectées follows the agreement rules for participles. When used with the auxiliary être, it agrees with the subject (as in passive constructions). When used with the auxiliary avoir, it agrees with a preceding direct object (for example: les substances que j’ai injectées dans le patient). Examples include: les solutions injectées dans l’organisme; les hormones injectées chez l’animal; les substances injectées ont été observées sur les échantillons.

Etymology traces injectées to the verb injecter, itself derived from Latin injicere, meaning to throw in or insert. The term is primarily employed in technical or clinical language to specify that a substance has been delivered via injection rather than by other routes such as oral administration or infusion.

Beyond medicine, injectées can appear in scientific descriptions of experiments where dyes, tracers, or drugs have been injected into tissues, gels, or systems to study diffusion, reactions, or uptake. The word thus conveys both action (injection) and result (the substance now being in the target medium).
