tvoených

"Tvoených" is not a standard word in Czech or Slovak; it appears to be a nonstandard or typographical variant of the past passive participle forms "tvořených" (Czech) or "tvorených" (Slovak), which mean "formed" or "created" when used adjectivally. The correct participle is derived from the verbs tvořit (Czech) and tvoriť (Slovak), both meaning "to form" or "to create."

In standard usage the participle functions as an adjective and agrees with the noun it modifies in gender, number and case. Common contexts include descriptions of composed or assembled things, for example expressions equivalent to "groups formed by..." or "structures created from...". Czech and Slovak differ slightly in spelling and diacritics: Czech uses the caron in "tvořených," while Slovak uses "tvorených."

The variant "tvoených" often arises from omission of diacritics, keyboard limitations, optical character errors, or phonetic misspelling. In digital text it may also reflect ASCII-only transcription or the result of automated transliteration. For clear communication, especially in formal writing, the standard accented forms appropriate to each language are recommended.
