Past tense morphemes are suffixes added to verbs to indicate that an action happened in the past. In English, the most common past tense morpheme is -ed, but there are others:
1. Regular Past Tense (-ed):
* Walked: walk + ed
* Played: play + ed
* Worked: work + ed
2. Irregular Past Tense:
* Went: go (no suffix)
* Saw: see (no suffix)
* Did: do (no suffix)
* Took: take (no suffix)
* Came: come (no suffix)
* Made: make (no suffix)
3. Other Past Tense Markers:
* -t: In some verbs, "ed" becomes "t" after a "d" or "t" sound (e.g., "wanted," "built").
* -en: Some verbs have an irregular past tense form with "-en" (e.g., "taken," "written," "chosen").
