Frequency
Hyphenated as
im‧pulse
Pronounced as (IPA)
/ˈɪmpʌls/
Etymology
Borrowed from Middle French impulser, from Latin impulsus. For spelling, as in pulse, the -e (on -lse) is so the end is pronounced /ls/, rather than /lz/ as in pulls, and does not change the vowel (‘u’). Compare else, false, convulse.
