Worksheet for identifying prefixes in words.

Let's solve the task from the worksheet titled "The Prefix Circle". The goal is to circle the prefix in each word listed.

A prefix is a letter or group of letters added to the beginning of a word to change its meaning. Common prefixes include *un-*, *re-*, *dis-*, *pre-*, *anti-*, *multi-*, *sub-*, *co-*, *ex-*, *bi-*, *tri-*, *quad-*, *octo-*, *pent-*, etc.

We’ll go through each word and identify the prefix.

🔹 Word List with Prefixes Identified:

1. anarchy → an-
(from Greek "an-" = without, no government)

2. agriculture → agri-
(from Latin "agri-" = field, farming)

3. democracy → demo-
(from Greek "demos" = people)

4. malnutrition → mal-
(means bad or poorly; e.g., "mal" as in "malfunction")

5. megaphone → mega-
(means large or big)

6. antibody → anti-
(means against)

7. centimeter → centi-
(means one hundredth)

8. subway → sub-
(means under)

9. reduction → re-
(means again or back)

10. bibliography → biblio-
(from Greek "biblion" = book)

11. international → inter-
(means between)

12. quadrangle → quad-
(means four)

13. undelete → un-
(means not or reverse)

14. exoskeleton → exo-
(means outside)

15. bicycle → bi-
(means two)

16. multiculturalism → multi-
(means many)

17. invaluable → in-
(means not — note: "invaluable" means "of such value that it cannot be measured", but the prefix is "in-")

18. discovery → dis-
(means apart, away, or reversal)

19. triangle → tri-
(means three)

20. milliliter → milli-
(means one-thousandth)

21. cooperative → co-
(means together)

22. television → tele-
(means far or distant)

23. precedent → pre-
(means before)

24. conference → con-
(means together)

25. nonsense → non-
(means not)

26. octagon → octa-
(means eight)

27. extraterrestrial → extra-
(means beyond or outside)

28. supersonic → super-
(means above or beyond)

29. pentagon → penta-
(means five)

30. dynamic → dy-? Wait — actually, no prefix here.
But let’s check: "dynamic" comes from Greek "dynamis" = power. There is no common prefix in this word.
However, some might argue "dy-" is a root, not a prefix. So dynamic has no prefix.

⚠️ Important: Not all words have prefixes. Some are just roots or compound words.

So for dynamic, there is no prefix — so nothing should be circled.

✔ Final Answer: Circle the prefix in each word

Here is the list with only the prefixes highlighted (as they would be circled):

1. anarchy → circle an
2. agriculture → circle agri
3. democracy → circle demo
4. malnutrition → circle mal
5. megaphone → circle mega
6. antibody → circle anti
7. centimeter → circle centi
8. subway → circle sub
9. reduction → circle re
10. bibliography → circle biblio
11. international → circle inter
12. quadrangle → circle quad
13. undelete → circle un
14. exoskeleton → circle exo
15. bicycle → circle bi
16. multiculturalism → circle multi
17. invaluable → circle in
18. discovery → circle dis
19. triangle → circle tri
20. milliliter → circle milli
21. cooperative → circle co
22. television → circle tele
23. precedent → circle pre
24. conference → circle con
25. nonsense → circle non
26. octagon → circle octa
27. extraterrestrial → circle extra
28. supersonic → circle super
29. pentagon → circle penta
30. dynamic → no prefix → do not circle anything

📝 Explanation:

- Prefixes are added to the beginning of words.
- Many of these prefixes come from Latin or Greek roots.
- Some words like dynamic may look like they have a prefix, but “dy-” is actually part of the root word (from “dynamis”).
- Words like bicycle, tricycle, quadrangle, pentagon, octagon use numerical prefixes.
- Words like anti, sub, re, un, dis, in, non, pre, co, tele, ex, inter, multi, centi, milli, mega, extra, super are common prefixes.

✔ Answer Summary: Circle the following prefixes in each word:
- an, agri, demo, mal, mega, anti, centi, sub, re, biblio, inter, quad, un, exo, bi, multi, in, dis, tri, milli, co, tele, pre, con, non, octa, extra, super, penta

And do not circle anything for dynamic.
