Model Answer
| S. No. | Word | Affixes | Stem |
|--------|------|---------|------|
| i. | Tries | -es | Try |
| ii. | Learning | -ing | Learn |
Stemming removes affixes (prefixes/suffixes) from a word to obtain its root/stem form.
- Tries → suffix -es is removed → Stem: Try
- Learning → suffix -ing is removed → Stem: Learn

Explanation
- Stemming is the process of stripping affixes (usually suffixes) from a word to get its base/stem. The stem may not always be a meaningful word (unlike lemmatization).
- For board exams, clearly identify the affix (e.g., -es, -ing) and the resulting stem.
- The examiner looks for the correct identification of suffix and the correct stem — 1 mark per row (½ for affix + ½ for stem, or 1 mark each row depending on the scheme).
