The abbreviation is the reduced writing of a word, although in reading it is pronounced in full. Example: prof. (read teacher). Abbreviations are indicated with a period at the end and are made by removing the final part (etc. for etcetera) or by removing letters from the middle of the word (mtro. for teacher). To understand what an acronym is, you must know what an acronym is. The acronym is the result of the first initials of a complex name, generally a type of institution, company, international organization... Example: UN (United Nations Organization). Acronym is the word resulting from an acronym that can be read like any other word. Example: UN, difference from PRD, which cannot be articulated orally in a regular way, but saying letter by letter.
The acronym is made up of the first letter of each word in a sentence and is usually capitalized: Example: IPN = Instituto Politécnico Nacional. The abbreviation is a short version of a word and can be lowercase. Examples: colony => col. minimum => min. Mexico => Mex. NOTE: The abbreviations have tildes (accents) when the complete word has it: )
