Adjective vs. Adverb worksheet with instructions to circle adjectives and underline adverbs, including a playful frog character.

Let’s go through each word one by one and decide if it’s an adjective (describes a noun) or an adverb (describes a verb, adjective, or another adverb).

We’ll circle the adjectives and underline the adverbs — but since we’re typing, I’ll list them clearly:

---

Row 1:
- mighty → describes something strong → adjective ✔
- heavy → describes weight of a thing → adjective ✔
- often → tells how frequently something happens → adverb _underlined_
- soon → tells when something will happen → adverb _underlined_

Row 2:
- blank → describes a surface or page → adjective ✔
- clearly → tells how something is done → adverb _underlined_
- promptly → tells how quickly something is done → adverb _underlined_
- only → can be tricky! Here it means “just” or “solely” → modifies verbs/adjectives → adverb _underlined_

Row 3:
- kind → describes a person’s nature → adjective ✔
- willingly → tells how someone does something → adverb _underlined_
- quickly → tells speed of action → adverb _underlined_
- fast → can be both, but here it’s describing how something moves → adverb _underlined_
*(Note: “fast” as adjective = “a fast car”; as adverb = “run fast”. In this context, likely adverb.)*

Wait — let’s double-check “fast”. Since the instruction says to circle adjectives and underline adverbs, and “fast” appears next to “quickly”, which is definitely an adverb, it’s safe to treat “fast” here as an adverb too.

But actually — in many grammar exercises, “fast” is accepted as both. However, looking at the pattern, words like “kind”, “blank”, “heavy” are clearly adjectives. Words ending in -ly are usually adverbs. “Fast” doesn’t end in -ly, but still functions as adverb here.

Actually — let’s check standard usage:

In “He runs fast” → fast = adverb
In “It’s a fast car” → fast = adjective

Since there’s no sentence context, we have to guess based on common usage in such worksheets. Often, “fast” is listed as an adverb in these lists when paired with “quickly”.

BUT — wait! Look at row 6: “loud” and “softly” — “loud” can be adjective (“loud noise”) or adverb (“speak loud”). Again, ambiguous.

To avoid confusion, let’s use this rule for this worksheet:

→ If the word typically describes a *thing* (noun), it’s an adjective.
→ If it describes *how, when, where, or how much* an action is done, it’s an adverb.

Also, many -ly words are adverbs — but not all (e.g., “friendly” is adjective). But in this list, most -ly words are adverbs.

Let’s continue carefully.

Row 4:
- openly → how something is done → adverb _underlined_
- closed → describes state of door/window → adjective ✔
- wet → describes something damp → adjective ✔
- damp → same as wet → adjective ✔

Row 5:
- costly → expensive → describes thing → adjective ✔
- free → no cost → describes thing → adjective ✔
- colorful → full of color → describes thing → adjective ✔
- aptly → appropriately → how something is done → adverb _underlined_

Row 6:
- fresh → describes food/air → adjective ✔
- freshly → how something is made/done → adverb _underlined_
- loud → can be adjective (“loud sound”) or adverb (“shout loud”) — again, ambiguous. But since “softly” is next to it and is adverb, maybe “loud” here is meant to be adjective? Wait — look at row 9: “loudly” is also there. So probably “loud” here is adjective, “loudly” is adverb.

Yes — that makes sense. So:
- loud → adjective ✔
- softly → adverb _underlined_

Row 7:
- new → describes age of thing → adjective ✔
- old → same → adjective ✔
- anciently → very rarely used, but means “in ancient times” → adverb _underlined_
- modern → describes style/time → adjective ✔

Row 8:
- large → size → adjective ✔
- tiny → size → adjective ✔
- freely → how something is done → adverb _underlined_
- kindly → how someone acts → adverb _underlined_
*(Note: “kindly” can be adjective too — “a kindly old man” — but here, since “kind” is already listed as adjective, and “kindly” is paired with “freely”, likely adverb.)*

Actually — “kindly” as adjective is less common. Most often it’s adverb. Let’s go with adverb.

Row 9:
- loudly → how something is said → adverb _underlined_
- oddly → strangely → how something is done → adverb _underlined_
- weird → strange → describes thing → adjective ✔
- soapy → covered in soap → describes thing → adjective ✔

Now let’s compile the final lists.

---

✔ Adjectives (circle these):

mighty, heavy, blank, kind, closed, wet, damp, costly, free, colorful, fresh, loud, new, old, modern, large, tiny, weird, soapy

Wait — did I miss any?

From Row 1: mighty, heavy
Row 2: blank
Row 3: kind
Row 4: closed, wet, damp
Row 5: costly, free, colorful
Row 6: fresh, loud
Row 7: new, old, modern
Row 8: large, tiny
Row 9: weird, soapy

That’s 19 adjectives.

Now adverbs:

often, soon, clearly, promptly, only, willingly, quickly, fast, openly, aptly, freshly, softly, anciently, freely, kindly, loudly, oddly

Wait — “only” — is it always adverb? Actually, “only” can be adjective too (“the only child”), but in general usage without context, it’s treated as adverb. And in this list, it’s grouped with other adverbs.

Also, “fast” — we decided adverb.

“anciently” — rare, but adverb.

So adverbs:

often, soon, clearly, promptly, only, willingly, quickly, fast, openly, aptly, freshly, softly, anciently, freely, kindly, loudly, oddly

That’s 17 adverbs.

Total words: 9 rows × 4 = 36 words. 19 + 17 = 36 — good.

But let me cross-verify a few tricky ones:

- “only”: In “I only eat apples” → adverb. In “She is the only student” → adjective. Without context, safest to call it adverb here since it’s not modifying a noun directly in the list.

- “fast”: As discussed, in “run fast” → adverb. Since no noun follows, assume adverb.

- “loud”: We called it adjective because “loudly” is separate. Makes sense.

- “kindly”: Called adverb. Acceptable.

Final Answer:

Adjectives (to circle):
mighty, heavy, blank, kind, closed, wet, damp, costly, free, colorful, fresh, loud, new, old, modern, large, tiny, weird, soapy

Adverbs (to underline):
often, soon, clearly, promptly, only, willingly, quickly, fast, openly, aptly, freshly, softly, anciently, freely, kindly, loudly, oddly
