suurendasid

Suurendasid is an Estonian verb form meaning "they increased." It is the simple past tense form used with a third-person plural subject, and it comes from the verb suurendama, which means to increase or enlarge. The infinitive form suurendama conveys the idea of making something larger, greater, or more extensive. The past tense form suurendasid is used to describe actions completed in the past by multiple subjects.

In use, suurendasid appears in sentences where a plural group has caused an increase in some quantity, scope, or level. It is typically transitive, taking a direct object that represents what was increased, often in the partitive or genitive case depending on sentence structure. Examples include: Ettevõtted suurendasid toodangu mahtu (Companies increased production volume); Nad suurendasid investeeringuid (They increased investments). The construction highlights a deliberate or measured change rather than a natural growth.

Etymology and related forms: suurendasid is derived from the root suur-, meaning large or big, combined with the verbal suffixes used to form the infinitive suurendama and the past plural suffix. Related forms include suurendasin (I increased), suurendasid (you or they increased, depending on person), and suurendama (to increase). The word is commonly found in media, reports, and academic writing to describe actions that enlarged quantities, budgets, or scopes.
