A stem is the intermediate form of a word between the lemma and its inflected surface form. It typically reflects the base pattern of a word before it’s conjugated or declined. Stemming is used in linguistic processing to group words with similar forms.

Example:

  • Lemma: رَحِمَ – to have mercy
  • Stem: رَحْم
  • Related forms:
    • رَحْمَة (raḥmah) – mercy
    • يَرْحَمُ (yarḥamu) – he shows mercy
    • الرَّحِيم (Ar-Raḥīm) – the Merciful
