peniejszym

Peniejszym is not a standard term in modern Polish. It is not listed in major dictionaries and is rarely found in published texts, suggesting that if it appears, it is either a misspelling, a nonce word, or a form borrowed from a dialect or historical text.

Linguistically, the ending -szym signals the instrumental singular masculine form of an adjective in Polish; peniejszym would thus be the instrumental of a hypothetical adjective peniejszy. Because there is no attested base form in reliable sources, the exact meaning of peniejszym is uncertain.

In practice, any use would likely aim to evoke archaic or regional flavor or would be corrected by editors in standard writing. The term remains speculative and unestablished in contemporary Polish usage.
