täidaks

Täidaks is the third-person singular present conditional form of the Estonian verb täita, meaning "to fill." It is used to express a hypothetical action or outcome in a sentence, often in clauses introduced by kui (if) or other condition-marking contexts.

Morphology and usage notes: The 3rd person singular present conditional is formed by adding the suffix -aks to the verb stem. For täita, the stem relevant to this form is täid- (the infinitive täita has the final -a). The result is täidaks. In full conjugation, other persons use related forms such as täidaksin (I would fill), täidaksid (you would fill), täidaksime (we would fill), and täidaksite (you all would fill). The stem may undergo minor phonetic adjustments in certain phonological environments, but täidaks remains the standard written form for the third person singular.

Typical contexts: Täidaks is used to describe hypothetical actions or outcomes. Examples include: "Ta täidaks kasti" meaning "He would fill the box." More complex sentences use kui or other conditional clauses, for example: "Kui ta täidaks vormid, saaks ta preemia" meaning "If he would fill the forms, he would receive a prize." The mood signals hedging or politeness and is common in written and spoken Estonian when discussing potential scenarios.

Relation to dictionaries and grammar: Täidaks is not a separate dictionary entry; it is a finite form of the lemma täita. Dictionaries list täita as the lemma, with conjugation tables showing forms such as täidaks for third-person singular conditional. This reflects Estonian verb morphology, where mood and person are marked within the verb itself rather than as separate words.
