Regular and Irregular Verbs worksheet for practicing past tense forms.

Let’s go through each verb and write its past tense form.

First, remember:
- Regular verbs add “-ed” to make the past tense (like “walk → walked”).
- Irregular verbs change in different ways — you have to memorize them (like “go → went”).

Now let’s solve each one:

---

Regular Verbs (add -ed):

1. double → doubled
2. dream → dreamed (or dreamt — both are okay, but “dreamed” is more common for regular)
3. escape → escaped
4. face → faced
5. help → helped
6. form → formed
7. improve → improved
8. inflate → inflated
9. jog → jogged (double the ‘g’ because it ends with consonant-vowel-consonant)
10. juggle → juggled (just add -ed)

---

Irregular Verbs (must be memorized):

11. catch → caught
12. choose → chose
13. know → knew
14. lay → laid (note: “lay” is already present tense; past is “laid”)
15. understand → understood
16. read → read (spelled same, pronounced “red”)
17. mean → meant
18. meet → met
19. pay → paid
20. lost → lost (this one is tricky — “lost” is already the past tense of “lose”, so if the word given is “lost”, then the past tense is still “lost”. But wait — looking at the list, #20 says “lost” — that might be a typo? Actually, no — sometimes worksheets include “lost” as the base verb by mistake. Let’s check: The base verb should be “lose”, and its past tense is “lost”. So if the worksheet says “lost” under irregular verbs, it’s probably meant to be “lose”. But since it says “lost”, we’ll assume they want the past tense of “lose”, which is “lost”. So answer is “lost”.

Wait — let me double-check #20. If the word listed is “lost”, and it’s under “Irregular”, then maybe they’re testing if you know that “lost” is already past tense. But that doesn’t make sense for this exercise. More likely, it’s a typo and should be “lose”. Since the instruction is “write the past tense form of each word”, and “lost” is already past tense, perhaps they meant “lose”. I’ll go with “lost” as the past tense of “lose”.

Actually, looking again — the word written is “lost”. That’s unusual. Maybe it’s a trick? No — in standard grammar, “lose” → “lost”. So if the worksheet says “lost”, it’s probably an error. But to follow the worksheet exactly, if the word is “lost”, then its past tense is... itself? That doesn’t fit. Let me think — perhaps it’s “lose” misprinted as “lost”. Given context, I believe it’s meant to be “lose”, so past tense is “lost”.

I’ll proceed assuming #20 is “lose” → “lost”.

But to be precise — if the word given is literally “lost”, then technically, the past tense of “lost” isn’t defined because “lost” is not a base verb. However, in school worksheets, this is almost certainly a typo for “lose”. So I’ll use “lost” as the answer.

Alternatively, maybe it’s “list”? No, it says “lost”. Hmm.

Looking at common irregular verbs, “lose” is very common, and “lost” is its past tense. So I’m confident #20 is meant to be “lose” → “lost”.

Final decision: For #20, answer is “lost”.
