Let's solve each section of this worksheet step by step and explain the reasoning behind each answer.

---

1. Prefixes: non-, dis-, un-

Instructions: Add one of the prefixes non-, dis-, or un- to the root words. These prefixes usually mean "not" or "opposite of."

We’ll go through each word:

| Root Word | Prefix | New Word | Explanation |
|------------------|--------|------------------|-----------|
| agree | dis- | disagree | "Not agree" → to disagree |
| willing | un- | unwilling | "Not willing" |
| appoint | dis- | disappoint | "Not appoint" (though note: *disappoint* is a real word, meaning to fail to meet expectations) |
| sense | non- | nonsense | "Not sense" → meaningless talk |
| worthy | un- | unworthy | "Not worthy" |
| negotiable | non- | non-negotiable | "Not negotiable" |
| grace | un- | ungraceful | "Not graceful" |
| fat | non- | non-fat | "Not fat" (common in food labels) |
| used | dis- | disused | "No longer used" |

✔ So, the completed list:
- disagree
- unwilling
- disappoint
- nonsense
- unworthy
- nonnegotiable
- ungrace
- nonfat
- disused

> Note: For "appoint", while "disappoint" is correct, it's worth noting that "dis-" here doesn't just mean "not", but rather "to take away from". Still, it's a valid use of the prefix.

2. Suffixes: -able, -ment, -ness

Instructions: Add one of the suffixes -able, -ment, or -ness to the root words.

Let’s analyze each:

| Root Word | Suffix | New Word | Meaning / Reasoning |
|-------------------|--------|------------------|---------------------|
| prob | -able | probable | "Capable of being true" → *probable* |
| content | -ment | contentment | "State of being content" |
| pass | -able | passable | "Able to be passed" (e.g., acceptable) |
| soft | -ness | softness | "Quality of being soft" |
| comfort | -ment | comfortment | (Less common; better: *comfort* + *able* = *comfortable*, but *comfortment* is archaic) → Actually, comfortable is more common. But since we need to pick one suffix, let's use -able: comfortable |
| move | -ment | movement | "Action of moving" |
| disappoint | -ment | disappointment | "State of being disappointed" |
| careless | -ness | carelessness | "Lack of care" |
| blind | -ness | blindness | "Condition of being blind" |

Now fill in the blanks:

- probable
- contentment
- passable
- softness
- comfortable
- movement
- disappointment
- carelessness
- blindness

✔ Final answers:
- probable
- contentment
- passable
- softness
- comfortable
- movement
- disappointment
- carelessness
- blindness

> Note: "Comfortment" is rare; "comfortable" is much more common. So using -able makes more sense.

3. Root Words

Instructions: Use the root words cycl (circular), graph (write/draw), and phon (sound) to create three new words for each by adding prefixes or suffixes.

Let’s build three words for each root.

---

#### Root: cycl (circular)

1. cycle – a circular motion or repeated event
2. cyclic – occurring in cycles
3. cyclone – a circular storm (from Greek *kyklos* = circle)

> ✔ Examples: cycle, cyclic, cyclone

---

#### Root: graph (write/draw)

1. graph – a chart or diagram (base form)
2. graphic – visual or written representation
3. autograph – a person’s own signature (auto = self, graph = write)
4. photograph – picture taken with light (photo = light, graph = draw/write)

> ✔ Examples: graphic, autograph, photograph

---

#### Root: phon (sound)

1. phone – a device for sound transmission
2. phonics – study of sounds in language
3. telephone – distant sound (tele = far, phone = sound)

> ✔ Examples: phone, phonics, telephone

---

✔ Final Answers for Section 3:

| cycl (circular) | graph (write or draw) | phon (sound) |
|------------------|------------------------|---------------|
| cycle | graphic | phone |
| cyclic | autograph | phonics |
| cyclone | photograph | telephone |
