Temporal - temporary

Do not confuse the adjectives temporal and temporary.

• Temporal means 'to do with time'. in a variety of senses - for more detail, see Temporal (meaning).
• Temporary (from the same root) means 'for a short time', 'not permanent'. A 'temporary typist', or temp for short, is an employee taken on to relieve other staff at busy times, replace them for short absences etc.; a 'temporary lieutenant' is an officer created for an emergency, usually for the length of a given war.

The adverbs temporally and temporarily can sound very similar in all realizations other than the most carefully spoken. The usual pronunciations in British RP (and therefore most academic speech in the UK) are:

• temporal: 'TEMP-er-el', IPA: /ˈtɛmp ^ər əl/;
• temporally: 'TEMP-er-el-y', IPA: /ˈtɛmp ^ər əl ɪ/
• temporary: 'TEMP-er-ery', IPA: /ˈtɛmp ər ər ɪ/;
• temporarily: 'TEMP-er-er-el[ly]', /ˈtɛmp ər ər əl ɪ/. Because this last can sound very similar to temporally: 'TEMP-er-el-y', IPA: /ˈtɛmp ər ər ɪ/ in all but careful speech (or even 'TEMP'r'ly',/ˈtɛmp ^ər ^əl ɪ/), the habit is growing of pronouncing it in the American fashion as 'temp-er-AIR-ill-y', /tɛmp ər ˈeər əl ɪ/.

Don't imagine any connection with (the Vale of) Tempe, pronounced 'TEM-py' IPA: /ˈtɛmp e (or ˈ)/, a narrow pass of strategic importance in north-eastern Greece.
