Grade 6 English worksheet focusing on prefixes, suffixes, and root words with interactive exercises.

Let’s go step by step through each part of the worksheet.

---

Part 1: Prefixes non-, dis- and un-

We need to add one of these prefixes — *non-*, *dis-*, or *un-* — to each root word to make a new word that means “not” or “the opposite.”

Let’s think about which prefix fits best with each word:

- agree → We say “disagree” (not agree). ✔
- willing → “Unwilling” is common (not willing). ✔
- appoint → “Disappoint” means to let someone down, but wait — actually, “disappoint” comes from “dis- + appoint”, yes. But note: “appoint” alone isn’t usually used as a root for “not appointed”. Actually, in this context, it’s likely expecting “disappoint” as the formed word. Let’s check others first.
Wait — maybe we should look at standard combinations:

Actually, let’s list them properly:

Root words given:
- agree → disagree
- willing → unwilling
- appoint → disappoint? Hmm… but “disappoint” is a real word, though its meaning is more “to fail to meet expectations” than just “not appoint”. Alternatively, “nonappointed” exists but is rare. In school worksheets, they usually expect common words. So probably “disappoint” is intended here.

But let’s double-check all:

Standard answers for Grade 6 level:

- agree → disagree
- willing → unwilling
- appoint → disappoint *(even if meaning shifts slightly, it’s commonly taught this way)*
- sense → nonsense or dissense? “Nonsense” is very common. “Dissense” is not really a word. So → nonsense
- worthy → unworthy
- negotiable → nonnegotiable (common phrase)
- grace → disgrace
- fat → unfat? Not common. Wait — “nonfat” is used (like nonfat milk). So → nonfat
- used → unused

So final choices:

- _dis_ agree
- _un_ willing
- _dis_ appoint
- _non_ sense
- _un_ worthy
- _non_ negotiable
- _dis_ grace
- _non_ fat
- _un_ used

✔ All are real, commonly used words.

Part 2: Suffixes –able, -ment and -ness

Add one of these suffixes to each root word to form a new word.

Let’s try each:

- prob → probable? But suffixes given are –able, -ment, -ness. “Probable” uses “-able”, so → probable
Wait — spelling: “prob” + “able” = “probable” — correct.

But note: sometimes “prob” might be short for “probability”, but here we’re adding suffixes directly.

Actually, let’s do each carefully:

Given root words:

Column 1:
- prob → probable (-able)
- soft → softness (-ness)
- disappoint → disappointment (-ment)

Column 2:
- content → contentment (-ment) OR contented? But suffixes are only –able, -ment, -ness. “Contentment” is good. Also “contentness”? Rare. So → contentment
- comfort → comfortable (-able)
- careless → carelessness (-ness)

Column 3:
- pass → passable (-able)
- move → movement (-ment)
- blind → blindness (-ness)

Check:

- prob + able = probable ✔
- soft + ness = softness ✔
- disappoint + ment = disappointment ✔
- content + ment = contentment ✔
- comfort + able = comfortable ✔
- careless + ness = carelessness ✔
- pass + able = passable ✔
- move + ment = movement ✔
- blind + ness = blindness ✔

Perfect.

Part 3: Root words — cycl, graph, phon

Make three words from each root by adding a prefix or suffix.

Root: cycl (circular)

Possible words:
- bicycle (bi- + cycle) — but “cycle” comes from “cycl”
- tricycle
- cyclone
- recycle
- cyclical

We can pick any three common ones:

→ bicycle, tricycle, cyclone
OR → recycle, cyclical, cyclometer — but keep it simple.

Best for Grade 6:
1. bicycle
2. tricycle
3. cyclone

Root: graph (write or draw)

Words:
- photograph (photo + graph)
- autograph (auto + graph)
- biography (bio + graph)
- graphic
- telegraph

Pick three:

1. photograph
2. autograph
3. biography

Root: phon (sound)

Words:
- telephone (tele + phone)
- microphone (micro + phone)
- symphony (sym + phony) — close enough
- phonics
- euphony

Common ones:

1. telephone
2. microphone
3. phonics

All valid.
