Polish Adverb Formation
Adverb are formed from adjectives by adding either an e or an o to the end of the adjective. There is no clear-cut rule to determine which letter to add, but here are some general rules:
– If the adjective stem ends with a hardened or soft consonant, or k, g, or ch, always add o. Also, always add o if the adjective ends with an i.
– If the adjective stem ends with a hardened consonant (except, k, g, and ch), sometimes you add an o, sometimes you an e. In general, stems ending with n tend to take an e adverb ending.
When an e is added, the previous consonant softens.
Adverbs which are derived from adjectives ending with -ski take the u ending and are always followed by the preposition po.
Polish adverbs are normally placed before the word they are modifying, but can be placed after to add emphasis.
