l → o Alternation

L and O Alternations

Level 3

O in one form can correspond to l in another.

How It Works

In many masculine singular active participles, an older final l appears as o, while other gender forms keep l: čitao, čitala, čitalo.

Compare noun forms such as orao and orla, or pepeo and pepela. Some words combine this change with the loss of a vowel.

This is a pattern to recognize in known word families, not a spelling instruction to turn every final l into o. Learn the masculine and feminine participles together, and check noun case forms individually.

Examples (3)

  1. Ivan je čitao novine.

    Ivan was reading the newspaper.

    The masculine singular participle ends in -o.

  2. Ana je čitala novine.

    Ana was reading the newspaper.

    The feminine form keeps l before -a.

  3. U peći ima pepela.

    There is ash in the stove.

    Pepela is a genitive form of pepeo.
