Another class of exceptions is verbs with the conditional endings , etc. These endings are not counted in determining the position of the stress; for example, ('I would do') is stressed on the first syllable, and ('we would do') on the second. According to prescriptive authorities, the same applies to the first and second person plural past tense endings , although this rule is often ignored in colloquial speech (so 'we did' should be prescriptively stressed on the second syllable, although in practice it is commonly stressed on the third as ).Phonetics and Phonology of lexical stress in Polish verbs, Dominika Oliver, Martine Grice, Institute of Phonetics, Saarland University, Germany These irregular stress patterns are explained by the fact that these endings are detachable clitics rather than true verbal inflections: for example, instead of ('whom did you see?') it is possible to say – here retains its usual stress (first syllable) in spite of the attachment of the clitic. Reanalysis of the endings as inflections when attached to verbs causes the different colloquial stress patterns. These stress patterns are considered part of a "usable" norm of standard Polish - in contrast to the "model" ("high") norm.
