Many writers wonder about signalling or signaling because the words look almost the same. Both are used to mean to provide an indication or message though it is spelt differently depending on your location. Signalling is a British English normative, whereas signaling is an American English normative.
The knowledge of the distinction makes your writing accurate and clear. The inappropriate form can be confusing to the readers particularly in the professional, academic or technical context. This guide explains signalling or signaling in detail, with examples, common mistakes & practical tips.
Define Signalling
Signalling is the British English form of the word. It means giving a sign, message, or indication. This can be done in many contexts:
- Traffic and driving
- Digital communication systems
- Body language
- Biological processes
- Business or strategy communication
Example:
- The driver was signalling before turning.
- She was signalling approval with a nod.
The spelling follows British conventions, where the final “l” is doubled before adding “-ing.” This is standard for verbs ending with a vowel + “l.”
Define Signaling
Signaling is the American English form. The meaning is identical to signalling. The spelling drops the doubled “l” because American English often avoids doubling when the stress is not on the last syllable.
Example:
- The driver was signaling before turning.
- He was signaling that the meeting had started.
This version is preferred in the United States, including in professional, academic, and technical writing.
