apri·cot /ˈa-prə-ˌkät, ˈā-/
fore·head /ˈfȯr-əd, ˈfȯr-ˌhed/
Symbols enclosed by parentheses represent elements that are present in the pronunciation of some speakers but are absent from the pronunciation of other speakers, or elements that are present in some but absent from other utterances of the same speaker:
1om·ni·bus /ˈäm-ni-(ˌ)bəs/
ad·di·tion·al /ə-ˈdi-sh(ə-)nəl/
Thus, the above parentheses indicate that some people say /ˈäm-ni-ˌbəs/ and others say /ˈäm-ni-bəs/; some /ə-ˈdi-shə-nəl/ , others /ə-ˈdi-shnəl/.
When a main entry has less than a full pronunciation, the missing part is to be supplied from a pronunciation in a preceding entry or within the same pair of reversed slashes:
cham·pi·on·ship /-ˌship/
pa·la·ver /pə-ˈla-vər, -ˈlä-/
The pronunciation of the first three syllables of championship is found at the main entry champion. The hyphens before and after /ˈlä/ in the pronunciation of palaver indicate that both the first and the last parts of the pronunciation are to be taken from the immediately preceding pronunciation.
In general, no pronunciation is indicated for open compounds consisting of two or more English words that have own-place entry:
witch doctor noun
Only the first entry in a sequence of numbered homographs is given a pronunciation if their pronunciations are the same:
1re·ward /ri-ˈwȯrd/ verb
2reward noun
The absent but implied pronunciation of derivatives and compounds run on after a main entry is a combination of the pronunciation at the main entry and the pronunciation of the other element as given at its alphabetical place in the vocabulary:
— ab·ject·ness noun
— face off verb
Thus, the pronunciation of abjectness is the sum of the pronunciations given at abject and -ness; that of face off, the sum of the pronunciations of the two elements that make up the phrase.
FUNCTIONAL LABELS
