czstszymi

czstszymi is not a standard Polish word. It appears to be a misspelling or a non-diacritic rendering of the correct form częstszymi, which is the instrumental plural of the adjective częsty (frequent, common). In Polish orthography, diacritics are usually retained, and częstszymi is the proper spelling in contexts that require the instrumental plural.

The form częstszymi is used when describing nouns in the instrumental case in the plural and conveys the sense of “with more frequent” or “more frequent ones.” For example: z częstszymi problemami (with more frequent problems), z częstszymi spotkaniami (with more frequent meetings), or częstszymi przypadkami (more frequent cases). The adjective częsty has comparative and superlative forms, with częstszy as the comparative and najczęstszy as the superlative. The instrumental plural form for this comparative is częstszymi, which aligns with other Polish adjectives that form the comparative with a -sz- cluster.

Orthography and typographical notes: when diacritics are omitted, the correct non-diacritic rendering of częstszymi would be czestszymi. The spelling czstszymi (as provided in the query) is not recognized as a correct Polish form and would be considered an error or a highly unusual typographic simplification. If encountered in text, it is advisable to interpret it as a misspelling of częstszymi.

Related terms include częstszy, częstsza, and najczęstszy, which express the basic comparative and superlative meanings of frequency. In English, the equivalent is “more frequent” or “more common.”
