OA words are words that contain the vowel team 'oa', a pairing of two vowels that work together to produce one sound, most commonly the long 'o' sound heard in 'boat', 'coat' and 'road'. This pattern belongs to a category of spelling rules sometimes summarised by the phrase 'when two vowels go walking, the first one does the talking', because the 'o' carries the sound while the 'a' remains silent.

This page provides the most comprehensive guide to OA words available. It covers the sound and spelling rule behind the pattern, a complete OA words list organised by length including a OA words activity and FAQs.

What is the OA Vowel Team?

The OA combination is a vowel team, also called a vowel digraph: two vowels placed together that combine to produce a single vowel sound rather than two separate sounds.

OA as a Vowel Team vs Other Letter Combinations

Type	Example	What Happens
Short vowel	cat, dog	Single vowel, short sound
Long vowel with silent e	cake, bone	Vowel + consonant + silent e
Vowel team (OA)	boat, coat	Two vowels together, one sound
Vowel team (EE)	tree, feet	Two vowels together, one sound

The Sound of OA Words

The sound of OA words is consistent and reliable, making this one of the more dependable vowel teams for young readers to learn.

The Long O Sound in OA

The vast majority of OA words produce the long 'o' sound, the same sound heard in 'go', 'no' and 'bone'. This sound is created when the two vowels 'o' and 'a' sit together in a syllable.

o + a = the long o sound
/oʊ/

Pronounce it: 'oh' as in b-oat, c-oat, r-oad

Where OA Typically Appears

The OA vowel team most commonly appears in the middle of a word, between an initial consonant or consonant blend and a final consonant.

b + oa + t = boat
c + oa + t = coat
r + oa + d = road
fl + oa + t = float

The Spelling Rule behind OA Words

Understanding the spelling rule behind OA words helps students apply the pattern confidently to new and unfamiliar words.

The 'Two Vowels Go Walking' Rule

A common teaching rhyme used for vowel teams like OA states: 'When two vowels go walking, the first one does the talking.' In OA words, the 'o' is the vowel that 'talks' (produces the sound), while the 'a' remains silent.

Where OA Appears in a Word

The OA vowel team typically appears in the middle of single-syllable words, rarely at the very end. This is different from some other vowel teams (like 'ow', which can appear at the end of a word, as in 'snow').

Common position: consonant + OA + consonant (boat, coat, road, soap)
Less common position: OA at the start of a word (oak, oat, oath)
Rare position: OA at the end of a word (very few examples exist in standard English)
