Adding a prefix to the beginning of an English word changes it to a different word. For example, when the prefix un-is added to the word happy, it creates the word unhappy. The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre-(meaning "before"), both of which are derived from Latin roots.
If the prefix or suffix is negative, such as 'dis-' or -'less', the word can be called an orphaned negative. [ 2 ] Unpaired words can be the result of one of the words falling out of popular usage, or can be created when only one word of a pair is borrowed from another language, in either case yielding an accidental gap , specifically a ...
Unlike derivational suffixes, English derivational prefixes typically do not change the lexical category of the base (and are so called class-maintaining prefixes). Thus, the word do, consisting of a single morpheme, is a verb, as is the word redo, which consists of the prefix re-and the base root do.

The root language of a numerical prefix need not be related to the root language of the word that it prefixes. Some words comprising numerical prefixes are hybrid words. In certain classes of systematic names, there are a few other exceptions to the rule of using Greek-derived numerical prefixes.
As with a prefix code, the representation of a string as a concatenation of such words is unique. A bifix code is a set of words which is both a prefix and a suffix code. [8] An optimal prefix code is a prefix code with minimal average length. That is, assume an alphabet of n symbols with probabilities () for a prefix code C.
The Urdu alphabet (Urdu: اُردُو حُرُوفِ تَہَجِّی, romanized: urdū ḥurūf-i tahajjī) is the right-to-left alphabet used for writing Urdu. It is a modification of the Persian alphabet , which itself is derived from the Arabic script .
