Check any sound by age →How to use these TH word lists
TH is one of the latest sounds children master, and replacing it with /f/ or /d/ — fumb for thumb, dis for this — is a common pattern. Start with the word position selected by the SLP and pick a small group of words that fits the learner at their current practice level.
The lists check where the TH sound appears in each pronunciation, not just the spelling. They do not choose a treatment target or replace clinical judgment.
