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.

Pronunciation

• IPA^(key): /??mp?ls/
• Hyphenation: im?pulse
