How to tell which part of speech a word is
Most Part 5 word-formation questions can be answered from the ending alone, without knowing what the word means.
| Part of speech | Common endings | Example |
|---|---|---|
| Noun | -tion, -sion, -ment, -ness, -ity, -ance, -ence, -er, -or | implementation, reliability, supervisor |
| Verb | -ize, -ise, -ate, -en, -ify | prioritize, calculate, strengthen, verify |
| Adjective | -able, -ible, -ive, -al, -ous, -ful, -ic, -ant, -ent | affordable, effective, financial, consistent |
| Adverb | -ly | significantly, temporarily, accurately |
How to answer a word formation question in 10 seconds
- Cover the answer choices and look only at the words immediately before and after the blank.
- An article (a, an, the), an adjective, or a preposition before the blank means a noun goes in it.
- A blank sitting directly before a noun means an adjective goes in it.
- A blank modifying a verb, an adjective, or a whole clause means an adverb goes in it.
- A blank after a subject with no other verb in the clause means a verb goes in it.
- Only now read the choices and pick the one whose ending matches the slot you identified.
Frequently asked questions
What is a word family?
A word family is the set of words built from the same root — for example inform, information, informative, and informatively. TOEIC Part 5 tests whether you can pick the right member of the family for a given grammatical slot.
How do I find all the forms of a word?
Type any form of the word into the finder above. It matches on every form, so entering 'informatively' returns the same family as entering 'inform'.
Are all words ending in -ly adverbs?
No. Most are, but friendly, costly, timely, likely, and lively are adjectives. TOEIC uses these as distractors in adverb questions.
Which part of speech is tested most often in TOEIC Part 5?
Nouns and adverbs. A blank preceded by an article or an adjective almost always takes a noun, and a blank modifying a verb almost always takes an adverb.
Do I need to know what the word means to answer a word formation question?
Usually not. Word formation questions are answered from the grammar around the blank and the ending of each choice, which is why they are the fastest points to collect in Part 5.
Is this word formation finder free?
Yes. The finder runs entirely in your browser, requires no account, and has no usage limit.
