Feltöltend
Feltöltend is a Hungarian participial form derived from the verb feltölteni, meaning to fill up or to upload. In standard Hungarian the related present participle feltöltendő is used as an adjective meaning that something is to be filled or uploaded. The form feltöltend, without the final vowel, is not common in ordinary prose; it may appear in technical contexts, such as code, file names, or where diacritics are omitted, but the normative form is feltöltendő.
Grammatically, the suffix -endő attaches to a verbal stem to create a non-finite participle that denotes necessity
Usage examples include feltöltendő adatok (data to be uploaded) and feltöltendő űrlapok (forms to be filled out/uploaded).
