Glued Sounds: Why -ing, -ank, and -unk Are Taught as One Chunk

Try Sounding Out "Sing"

Here's a quick experiment. Sound out the word sing the way a beginning reader would - one letter at a time: /s/... /i/... /n/... /g/.

Say it fast. What did you get? Something like "sin-guh." Not sing.

Now try sank: /s/... /a/... /n/... /k/. You'll land on something closer to "san-k" with a flat /a/ - and that's not quite sank either.

This isn't your child failing at phonics. It's a place where letter-by-letter decoding genuinely breaks down - and it's exactly why reading programs teach glued sounds.

What Are Glued Sounds?

Glued sounds (also called welded sounds) are letter groups where the sounds fuse together so tightly that they can't be cleanly pulled apart. The child learns the whole chunk as a single unit instead of decoding each letter.

The classic glued sound families:

• -ng family: -ing (sing, ring), -ang (bang, sang), -ong (song, long), -ung (sung, hung)
• -nk family: -ink (sink, wink), -ank (bank, sank), -onk (honk), -unk (junk, trunk)
• The -all, -am, -an family: ball, tall / ham, jam / fan, man - where the vowel is subtly shaped by the consonant after it

If your child's school uses a structured phonics program, you may see these on a poster as "welded sounds" with the letters drawn touching each other. Same idea: these letters are a team, read as one.

Why Letter-by-Letter Sounding Out Fails Here

Phonics teaches children that letters map to sounds and sounds blend into words. That's true - and it's the right foundation, as we explain in How to Teach a Child to Read. So why carve out an exception?

Because of what the nasal sound does to the vowel.

The /n/ and /ng/ sounds are nasal - air flows through the nose. When a short vowel sits right before a nasal, the vowel gets pulled toward the nose too, and its sound changes. The i in sing is not the crisp short /ĭ/ of sit. Say sit and sing back to back and listen to the vowel: in sing it drifts toward a long-e-ish sound. Likewise, the a in sank isn't the /ă/ of sat - it's nasalized, halfway to a different vowel.

On top of that, ng isn't /n/ + /g/ at all. It's a single sound, /ŋ/, made in the back of the mouth - there's no separate /g/ to blend.

So a child who dutifully decodes s-i-n-g letter by letter is assembling sounds that literally are not in the word. They do everything right and still get the wrong answer. Do that a few times and a child starts to distrust sounding out - which is the last thing you want, since decoding is the engine of everything else.

The fix is honest and simple: teach the chunk. -ing says /ing/. All of it, at once, every time. Now sing is just /s/ + /ing/. Two units, blends perfectly, first try.

Minimal Pairs: The Best Discrimination Practice

Once a child knows the chunks, the next challenge is telling similar chunks apart - especially the sneaky -nk endings, where the /n/ is easy to miss by ear. The gold-standard exercise is minimal pair discrimination: word pairs that differ only in the glued sound.

• sink / sick - is there an /n/ hiding before the k?
• wink / wick - same question
• sank / sang - does it end in /k/ or the /ng/ sound?
• tank / tack, bang / bag

Show both words, say one aloud, and have your child point to the word they heard. Then flip it: point to a word and have them read it. Testing both directions is what forces precise attention to the distinguishing letters - a child can't coast on the first letter or a lucky guess. This is the same principle behind minimal-pair practice in the Orton-Gillingham approach: make the child's ears and eyes do the fine-grained work, because that fine-grained work is reading. Sweet Phonics builds these exact pairs - sink/sick, wink/wick, sank/sang - into its tap activities, so children practice the discrimination with instant feedback.

How Chunking Builds Fluency

There's a bigger payoff here than just rescuing sing.

Fluent readers don't process words letter by letter - they see chunks. A skilled reader looks at drinking and perceives dr + ink + ing in a glance, not eight separate letters. Glued sounds are often a child's first formal experience of chunk-reading, and the habit generalizes.

The math is compelling too. Learn the chunk -ank once and you've unlocked bank, tank, sank, rank, blank, thank, drank, crank, plank - a whole word family for the price of one pattern. Same for -ing, -unk, -all, and the rest. Each glued sound is a key that opens dozens of doors.

And because these chunks are everywhere - -ing alone appears in nearly every English sentence your child will ever read - automating them removes friction from almost every future book.

How to Practice Glued Sounds at Home

Teach the chunk with a gesture. Introduce -ing as one sound with a "gluing" motion - press your hands together as you say /ing/. The physical glue metaphor sticks with young kids.

Build word family ladders. Pick one chunk and climb: sing, ring, king, wing, bring, sting. Say the onset, say the chunk, blend. When one family is solid, switch chunks: sink, wink, pink, think.

Play the minimal pair pointing game. Write sank and sang on paper. Say one; your child points. Swap roles - kids love being the caller, and reading the word aloud to quiz you is decoding practice in disguise.

Hunt for -ing in the wild. During bedtime reading, have your child spot every -ing word on the page and read the chunk before the whole word: "/ing/... jumping!"

Don't ask them to segment the glue. If a spelling program asks your child to tap out sing as four separate sounds, gently adapt: tap /s/ then /ing/. Segmenting a glued sound into pieces that don't exist just recreates the original problem.

The Short Version

Glued sounds - -ing, -ang, -ong, -ung, -ank, -ink, -onk, -unk, and the -all/-am/-an family - are letter teams that must be read as one unit, because the nasal sound changes the vowel and letter-by-letter decoding produces the wrong word. Teach each chunk whole, sharpen it with minimal pairs like sink/sick and sank/sang, and enjoy the side effect: a child who reads in chunks is a child on the road to fluency.
