recommended

Recommended is the past participle of the verb to recommend and an adjective used to indicate that something is advised, suggested, or regarded as appropriate by an authority, expert, or consensus. It signals guidance that is considered prudent or beneficial, rather than mandatory.

As an adjective, recommended precedes a noun to specify the advised option or quantity, such as the recommended dose, the recommended daily intake, or the recommended reading list. It can also describe guidance that is officially endorsed or widely accepted in a given field, although the level of obligation can vary from guidance to regulation.

Grammatically, recommended is also the past participle form used in verb phrases. For example, in perfect tenses one might say, The doctor has recommended daily exercise. In passive constructions, The dose is recommended at 10 mg per day. In these uses, it functions as part of a verb phrase rather than as a modifier.

Common contexts for the term include medicine and pharmacology (dosage guidance, treatment recommendations), nutrition (daily intake recommendations), consumer guidance (recommended retail price, recommended products), and standards or best practices (recommended practices or guidelines). The word often conveys authority while stopping short of an obligation.

Etymology: recommended derives from the verb recommend, which comes from Old French recommander and Latin recommandare. Related terms include recommendation and advisable, which capture related notions of guidance and suitability.
