toetamast
Toetamast is not a widely used term in English-language reference works. It is sometimes encountered in discussions of Estonian grammar as a non-finite verb form thought to be derived from the verb toetama, meaning “to support.” In that analytical sense, toetamast would be related to non-finite forms that convey action without subject-verb agreement, aiding the description of how sentences connect clauses or express ongoing or prospective activity.
Etymology and morphology: The form appears to combine the stem toeta- with the suffix -mast, a pattern
Usage: In everyday Estonian, the act of supporting is usually expressed using related forms such as toetamine
