The Origin of Signalling or Signaling

The word comes from the noun “signal,” which has Latin roots (signum, meaning sign or mark). When verbs were formed from nouns ending in -l, spelling rules developed differently over time.

British English kept the rule of doubling the “l” before adding -ing.
American English simplified spelling and dropped the extra l.

That is why both forms exist today.
