Arrange the following pairs of partial homonyms according to the traditional classification a (homographs), b (homophones), c (homoforms), fill in the blanks with your answers. note: every group may contain different number of homonyms. 1. night (n.) - knight (n. ) 2. rose (n.) - rose (past end. of rise) 3. son (n.) - sun (n) 4. pension (n.) - pension (n. ) 5. row (n.) - row (n.) 6. tear (n. ) - tear (v. ) 7. pair (n.) - pear (n.) 8. wind (v.) - wind (n. ) 9. left (adj. ) - left (past end. of leave) 10. plain (adj. ) - plane (n.) statistic.

Traditional classification of homonyms categorizes them into three types: homographs (words that are spelled the same but have different meanings and may or may not be pronounced the same), homophones (words that have the same pronunciation but different spellings and meanings), and homoforms (words that have both the same spelling and pronunciation but different meanings). Let's go through each pair and determine their classification.

1. night (n.) - knight (n.)
These words have different spellings, meanings, and pronunciations. Therefore, they are not homographs, homophones, or homoforms.

2. rose (n.) - rose (past end. of rise)
These words have the same spelling but different meanings and pronunciations. They are homographs because they are spelled the same.

3. son (n.) - sun (n)
These words have different spellings, meanings, and pronunciations. Therefore, they are not homographs, homophones, or homoforms.

4. pension (n.) - pension (n.)
These words have the same spelling but different meanings and pronunciations. They are homographs because they are spelled the same.

5. row (n.) - row (n.)
These words have the same spelling and pronunciation but different meanings. They are homoforms because they have the same spelling and pronunciation.

9. left (adj.) - left (past end. of leave)
These words have the same spelling but different meanings and pronunciations. They are homographs because they are spelled the same.

10. plain (adj.) - plane (n.)
These words have different spellings and meanings but the same pronunciation. They are homophones because they have the same pronunciation.

In summary, the pairs can be categorized as follows:
- Homographs: rose, pension, left
- Homophones: plane
- Homoforms: row, wind
