different between impulse vs propulsion
impulse
English
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
