Compound Consonants (ch, nh, th)
Grammar Rule in 30 Seconds
Vietnamese uses digraphs like 'ch', 'nh', and 'th' to represent single, unique sounds that differ from English.
- Ch: A sharp, palatal sound like 'ch' in 'cheese' (e.g., 'cha').
- Nh: A nasal sound like 'ny' in 'canyon' (e.g., 'nhà').
- Th: An aspirated 't' sound, not a 'th' like 'the' (e.g., 'thịt').
