About Final S words
Because the S ending marks grammar, an error here has two possible sources. A child who omits it may be unable to produce a final /s/, or may not yet be marking plurals and third person at all — an articulation question and a morphology question that look identical on a word list.
Only the endings that are genuinely voiceless appear here. After a voiced sound the same written -s is pronounced /z/, which is why dogs and runs sit on the final Z list while cats and walks stay on this one — a distinction spelling hides completely.
Practising Final S
Single-syllable nouns with a lexical S, such as bus and house, isolate the articulation without the grammar. Once that is stable, the plural entries let you check whether the ending survives when it also has to carry meaning.
Acquisition ages: Crowe & McLeod (2020), American Journal of Speech-Language Pathology. Educational content — an SLP chooses the target for a specific child.

- How many words have /s/ in the final position?
- Our dictionary lists 231 final /s/ words suitable for speech therapy practice.
- What are some example final /s/ words?
- Examples include ace, base, bless, brass, bus, chase, choice, class.
- Why is dogs not on the final S list?
- Because dogs ends in a /z/ sound, not /s/. English pronounces the plural -s as /z/ after voiced sounds, so dogs, cars, and runs appear on the final Z list even though all are spelled with s.
- How do I tell an articulation error from a grammar error?
- Compare a lexical S with a grammatical one. If a child says bus correctly but drops the S in cats, the ending is more likely a morphology issue than a placement issue. An SLP assessment separates the two properly.
