f / ff / dd / th

F, FF, DD and TH

Level 1

Watch these four letters: f = v (afal), ff = f (ffordd), dd = th in "this" (ddoe), th = th in "thin" (cath).

How It Works

F sounds like v: afal (apple), fi (me), fawr in Diolch yn fawr (Thank you very much).

Ff sounds like f: ffordd (road), ffrind (friend), coffi (coffee), hoffi (to like).

Dd sounds like the th in "this": ddoe (yesterday), dydd (day), Caerdydd (Cardiff). Your voice is on, and the tongue touches the top teeth.

Th sounds like the th in "thin": cath (cat), wyth (eight), wythnos (week). No voice, just air.

A handy clue: an f or dd at the start of a word is often a changed letter. Bara (bread) becomes fara and mam (mum) becomes fam after some words, and desg becomes ddesg. See soft mutation. You will also meet ph, which sounds like f. It almost always comes from a changed p, as in halen a phupur (salt and pepper); see aspirate mutation.
