Learn English – What prefix means “during”

Times:

1. Dawn refers to the time around the actual solar event that is sunrise.

2. Morning refers to any time before noon, so 1am is still the morning.

3. Very early morning is sometimes known as "the small hours" (or any regional variant of those words). The actual time is variable, although you will probably provoke a laugh from working people if you refer to any time after 7am in that way (and probably any time after 6am).

4. Noon refers to 12pm (exact midday) and the time just around it. 1101 is not noon.

5. Afternoon refers to the time after Noon and before the Night. "Good afternoon" is only used after noon.

6. Dusk corresponds to dawn, and refers to the event of the sun setting.

7. Evening is variable in its usage, and is tied both to work schedules and the solar time. It's pretty much always correct to refer to the part of the day when the light begins to wane as "evening".

8. Night refers to the time after sunset. Accordingly, it can be both morning and night (this being pretty much the definition of the small hours).

9. Midnight refers to exactly 0000/2400 hours, and the time just around it. 2301 is not midnight.

10. "Good night" does not mean "have a good sleep". It is used as a farewell when it is late, whether anyone is planning on going home or not.

Meals:

1. Lunch is a meal taken between breakfast and the evening meal (howsoever called). It is not tied to any specific time beyond that.

2. The main evening meal may be called "dinner", "supper", or "tea" depending on regional dialect and class. "Dinner" is probably the most neutral option in most dialects (although in some dialects it means the main meal of the day even if that was lunch, or it may mean something else). If a second evening meal is taken, or a very late evening meal is taken, it might be called supper in distinction to dinner. This is not so common any longer.

3. "Afternoon tea" is a specific meal. Its defining feature is not really that it is taken in the afternoon, but rather the elements it is composed of: it will be a short snack, usually of tea or coffee and a sweet or savory baked good. "Morning tea" is the corresponding snack in the morning.

We are not "fixing" you, because you are not broken. We are correcting you in so far as we think you are wrong.

Cambro- is the traditional form; the OED defines it in part as:

…used as combining form in the sense ‘pertaining to Cambria, Welsh’.

It’s never been common, but has clung on tenaciously over the years, in cambrophone, cambro-centric, Cambro-American, and the like. (It’s much more common in geological use, where it refers to the Cambrian Period.)

However, few apart from classicists or historians will understand it. An alternative option is Cymru- or Cymro-. This is less traditional, but usage on the internet and in British newspapers suggests it’s probably about as common today; and it has the great advantage that most Brits, and certainly anyone who’s lived in or near Wales, will understand it immediately. So if you don’t mind creating etymological Frankensteins, this is what I’d recommend.
