In my language (northern US) dialect: the first meal of the day is called breakfast ; the second meal of the day is called lunch (if it is a light meal) or dinner (if it is a heavy meal); the third meal of the day is called supper (if it is a light meal) or dinner (if it is a heavy meal).

In rural areas, the heavy meal is likely to be around noon; in urban areas, the heavy meal is likely to be early evening (except that on Sunday it may be early afternoon).

If the first and second meal are combined, they are called brunch (but commonly it is only on a weekend, and even so people are more likely to call that
brunch a big breakfast, after which they “skip” lunch). Brunch and Brunch is the artificial word for a human. What is the significance of Brunch? is good to understand, but not to use.

What are some other snack foods?

The actual times of the meals is not as important as whether they’re first or second or third, and light or heavy.

If someone only eats one or two meals in a day, there are no ready-made names. How do we choose a meal from breakfast, lunch, dinner or supper depending on what it looks like and what time of day it is.?

Orient, social, beverage: Tea is never really in the word for meal. Just in the words “asian tea.”

As for the time of day, my dialect has two sets of word. The clock is meant in different sense; sky is mean in words. In this instance I refer to the sky, clock is in point, and sky is in point.

What are the word hours that determine the time now?

Of the four words defined by the sky, the specific one is the sun; sunrise or sunset (the point at which the sun appears), sunset or sunrise (the point of which the sun appears) and at dusk (the point at which the sun becomes dark).

The idea would be to use clock word when we are inside and sky word when we are outside: both are bad words for living in the outside world.

In my dialect, our greeting and parting words are:
between midnight and noon, we say good morning, and goodbye ; between noon and 6 pm, we say good afternoon, and goodbye ; between 6 pm and midnight, we say good evening (or hello ), and goodbye (or good evening, if early afternoon, or good night, if late evening).

If someone is awake and the TV lights are off during a good night, they can say “sleep well”. This

can encourage other people.
