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 look at each word:

- agree → The opposite is *disagree* (we say “I disagree,” not “unagree” or “nonagree”)
- willing → The opposite is *unwilling* (“He is unwilling to help”)
- appoint → The opposite is *disappoint*? Wait — actually, “disappoint” means to let someone down, which isn’t exactly the opposite of “appoint.” But in this context, since we’re using common prefix patterns, *disappoint* is accepted as formed with “dis-”. However, note: “appoint” doesn’t have a direct opposite like “unappointed” — but “disappoint” is a real word. Let’s check others first.

Actually, let’s think again:
The instruction says: “Add one of the prefixes non-, un- or dis- to the following root words” — meaning we are forming real English words.

So:

- agree → disagree
- willing → unwilling
- appoint → disappoint? Hmm… “disappoint” comes from “dis- + appoint”, yes — it’s a valid word. Even though its meaning shifted over time, it’s still correct here.
- sense → nonsense (common phrase) OR unsense? No — “nonsense” is the right one.
Wait — “sense” can take “non-” → nonsense. Also “insensitive” uses “in-”, but we only have non/dis/un. So nonsense.
But wait — “sense” can also be “unsensed”? Not really used. Best fit: nonsense

Hold on — let’s list all properly:

Root words given:
- agree → disagree
- willing → unwilling
- appoint → disappoint (yes, standard word)
- sense → nonsense (most common; “unsense” isn’t a word)
- worthy → unworthy (yes — “he is unworthy”)
- negotiable → nonnegotiable (common term — e.g., “This offer is nonnegotiable”)
- grace → disgrace (yes — “bring disgrace”)
- fat → nonfat (as in “nonfat milk”) — could also be “unfat”? No, not a word. So nonfat
- used → unused (yes — “an unused room”)

Wait — let’s double-check “appoint”: Is “disappoint” really the opposite of “appoint”? Actually, no — “appoint” means to assign a role, “disappoint” means to fail expectations. But historically, “disappoint” did mean “to remove from office”, so it’s acceptable for this exercise.

Alternatively, maybe they expect “unappointed”? That’s also a real word — meaning “not appointed”. Which one fits better?

Looking at the pattern: We’re supposed to use non-, dis-, or un-. Both “disappoint” and “unappointed” are possible. But “disappoint” is more commonly taught as a prefixed word in elementary grades.

However, let’s see what makes most sense across all:

Let me re-list with best matches:

1. agree → disagree
2. willing → unwilling
3. appoint → disappoint (accepted in curriculum)
4. sense → nonsense
5. worthy → unworthy
6. negotiable → nonnegotiable
7. grace → disgrace
8. fat → nonfat
9. used → unused

Yes — these are all standard words taught at Grade 6 level.

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

We add one of these suffixes to the end of each root word.

Rules:
- -able: turns verb/adjective into adjective meaning “capable of being…”
- -ment: turns verb into noun meaning “action or result”
- -ness: turns adjective into noun meaning “state or quality”

Now apply:

- prob → probably? No — we need to form a word with -able, -ment, or -ness.
“prob” is short for “problem”? Or “probable”? In context, likely “probable” → but we start with “prob”.
Actually, “prob” alone isn’t a full root — but in worksheets, sometimes they abbreviate. Likely meant:
→ probable? But we must add suffix to “prob”.
Wait — perhaps it’s “prove”? No. Let’s think of common words:

Actually, looking at the layout:

It says:
prob____
content____
pass____
soft____
comfort____
move____
disappoint____
careless____
blind____

These are roots. Let’s match:

- prob → probability? Too long. Maybe provable? Yes — “provable” = able to be proven. So -able
- content → contentment (noun — state of being content) → -ment
- pass → passable (adjective — good enough) → -able
- soft → softness (noun — quality of being soft) → -ness
- comfort → comfortable (adjective) → -able
- move → movement (noun) → -ment
- disappoint → disappointment (noun) → -ment
- careless → carelessness (noun) → -ness
- blind → blindness (noun) → -ness

Check:

- prob → provable ✔
- content → contentment ✔
- pass → passable ✔
- soft → softness ✔
- comfort → comfortable ✔
- move → movement ✔
- disappoint → disappointment ✔
- careless → carelessness ✔
- blind → blindness ✔

Perfect.

Part 3: Root words — cycl, graph, phon

We need to make THREE words from each root by adding either a prefix or a suffix.

Given meanings:
- cycl = circular
- graph = write or draw
- phon = sound

Let’s brainstorm:

cycl (circular)
Possible words:
1. bicycle (bi- = two, cycle = wheel → two wheels)
2. tricycle (tri- = three)
3. recycle (re- = again, cycle = go around → reuse)
4. cyclone (storm that spins in circles)
5. encyclopedia (encyclo- + pedia + -ia, but contains “cycl”?)

Better to pick simple ones:

→ bicycle, tricycle, recycle

Or: cyclone, cyclical, recycling

But let’s choose three clear ones:

1. bicycle
2. tricycle
3. recycle

(All contain “cycl” and relate to circular motion or repetition.)

graph (write or draw)
Words:
1. telegraph (tele- = far, graph = write → send writing over distance)
2. paragraph (para- = beside, graph = write → section of writing)
3. autograph (auto- = self, graph = write → your own signature)
4. photograph (photo- = light, graph = draw → picture drawn with light)
5. graphic (adjective form)

Pick three:

→ telegraph, paragraph, autograph

Or simpler: graph, graphics, biography? Wait — “biography” has “graph” too.

But let’s stick with:

1. telegraph
2. paragraph
3. autograph

phon (sound)
Words:
1. telephone (tele- = far, phon = sound → hear sound from far away)
2. microphone (micro- = small, phone = sound → device to amplify small sounds)
3. symphony (sym- = together, phony = sound → many sounds together)
4. phonics (study of sounds in language)
5. euphony (eu- = good, phony = sound → pleasant sound)

Pick three:

→ telephone, microphone, symphony

Or: phonics, euphony, cacophony — but maybe too advanced.

Stick with:

1. telephone
2. microphone
3. symphony
