Answer – Terms such as NASA, CD-ROM, WiFi and ASAP are examples of acronyms.
Explanation:
The precise definition of the word ‘acronym’ is a subject of some debate among lexicographers. It is widely agreed that acronyms, like abbreviations, are short forms of phrases or words using letters – initials or otherwise – from the words involved. However, some dictionaries insist that in order for the word acronym to be applied, the resulting short form should be able to be pronounced as a word. For example, NASA (na-sa), WiFi (wai-fai) and ASAP (a-sap) are pronounced as words.
On the other hand, abbreviations like FBI and BBC are not. The names of their individual letters are pronounced (eff-bee-ai and bee-bee-cee). Certain dictionaries and style guides include short forms like these under the definition of acronym as well.
