There is a request for comment at Talk:Optical telegraph#Request for comment on meaning of semaphore which affects this article. SpinningSpark 08:01, 14 August 2021 (UTC)[reply]

In the discussion you've linked to, they seem to adopt the meaning "signalling device with arms" as their definition of "semaphore".
I think it's fine for words to have different meanings in different contexts; but I find the definition adopted here to be startlingly broad. For example, per the definition the lede, a mirror/sunlight signalling device is definitely a semaphore, but so is the optical hookup between my CD and amp.
The citations for the definition given in the lede could be improved; one is Britannica, and the other is something called "FactMonster", which I've not observed anything on WP being cited-to before.
I came here to find out about the semaphore alphabet, so I guess I'm off to Flag semaphore. Ah, rabbit-hole -> Optical telegraph; they distinguish two types - a shutter telegraph (which by our definition is a semaphore) and a "semaphore telegraph" (one with arms).
So there's an implied definitional conflict between these articles. I don't know what to suggest, but I don't like leaving this kind of confusion lying around, without some kind of explnation.
That is, if there are diverse opinions about what a semaphore is, that is a fact that belongs in the article.

A tautology is a taugology

This interesting (?) sentence appears in this article:

A hydraulic telegraph is either of two different semaphore systems involving a hydraulic-telegraph.

Once in the past, the article titled Traditional Brazilian medicine began by saying "Traditional Brazilian medicine is the traditional medicince of Brazil." Somehow this present instance doesn't seem as egregious but it probably merits an honorable mention. Michael Hardy (talk) 02:31, 20 February 2022 (UTC)[reply]

Requested move 23 January 2024

– I'm struggling to understand how this could be considered the primary topic of "semaphore". Semaphore (programming) gets twice as many page views and is at least as well represented (compared to all signaling device usage) in reliable sources such as those accessed via Google Scholar or Google Books. There are several other uses on the dab page that readers may well be looking for. (t · c) buidhe 17:18, 23 January 2024 (UTC) — Relisting. BilledMammal (talk) 01:11, 31 January 2024 (UTC)[reply]
