Prawidowym

Prawidowym is not a standard form in Polish. The usual, grammatically correct instrumental singular is prawidłowym, which is derived from the adjective prawidłowy meaning correct, proper, or in line with rules. The form prawidowym would be considered a misspelling or nonstandard variation, since it omits the letter ł that is essential to the correct word.

Etymology and meaning: prawidłowy comes from the root praw- connected to law, right, or correctness, and the suffix -owy that marks adjectives. The word conveys conformity with rules, standards, or truth. In everyday use, prawidłowy describes things that are proper, accurate, or properly functioning, such as prawidłowy proportions, prawidłowy wynik, or prawidłowy stan techniczny.

Orthography and usage: in formal Polish, one should write prawidłowy, prawidłowego, prawidłowemu, prawidłowym, etc., depending on grammatical case. The adverb is prawidłowo. The form prawidowym appears outside standard norms and is typically the result of a misspelling, a typographical error (especially when the ł key is difficult to type) or informal writing. Standard dictionaries do not recognize prawidowym as a correct variant.

Examples of correct usage include: prawidłowy wynik (correct result), utrzymanie prawidłowego stanowiska (maintenance of the proper position), działania zgodne z prawidłowym modelem (actions in accordance with the correct model). For learners, focusing on the spelling with ł ensures proper agreement across cases and genders.

In summary, prawidłowy is the correct root, and prawidłowym is the proper instrumental form; prawidowym is regarded as an incorrect spelling rather than a separate term.
