# Simple video lesson on what alphabetical order is

### Chapters

This video lesson is a brief one and will show you what alphabetical order is. You can later practise with some worksheet and quizzes on this site.

From Wikipedia

https://en.wikipedia.org/wiki/Alphabetical_order

Alphabetical order is a system whereby strings of characters are placed in order based on the position of the characters in the conventional ordering of an alphabet. It is one of the methods of collation.

To determine which of two strings comes first in alphabetical order, their first letters are compared. If they differ, then the string whose first letter comes earlier in the alphabet is the one which comes first in alphabetical order. If the first letters are the same, then the second letters are compared, and so on. If a position is reached where one string has no more letters to compare while the other does, then the first (shorter) string is deemed to come first in alphabetical order.

Capital letters (upper case) are generally considered to be identical to their corresponding lower-case letters for the purposes of alphabetical ordering, though conventions may be adopted to handle situations where two strings differ only in capitalization. Various conventions also exist for the handling of strings containing spaces, modified letters (such as those with diacritics), and non-letter characters such as marks of punctuation.

The result of placing a set of words or strings in alphabetical order is that all the strings beginning with the same letter are grouped together, and within that grouping, all words beginning with the same two-letter sequence are grouped together; and so on. The system thus tends to maximise the number of common initial letters between adjacent words.
