Phonetics and the IPA 2, Exercise 2: place of the first sound

pin    [p]  bilabial      both lips
fan    [f]  labiodental   lower lip + upper teeth
thin   [θ]  dental        tongue tip/blade + upper teeth
ten    [t]  alveolar      tongue tip/blade + alveolar ridge
ship   [ʃ]  postalveolar  tongue blade + area just behind the ridge
key    [k]  velar         tongue body + soft palate

Note: "key" is spelled with k; compare "cat". Both start with [k], but the
tongue touches slightly further forward before [iː] than before [æ]. That
fine detail is narrow transcription territory (Chapter 1).
