3. Abbreviation is the most widely used term for
a shortened or contracted form of a word or
phrase.
Abbreviations of single words are typically
formed using the first letter or letters of the
word. Example: Sr. = Senior
Many abbreviations for phrases, however, are
pronounced as words. Example: NATO for
N(orth) A(tlantic) T(reaty) O(rganization).
This type of abbreviation is called an
acronym.

5. ACRONYM
An acronym is a pronounceable word formed
mostly (but not always) from the initial
letters of a descriptive name or title.
Example: TYVM = Thank You Very Much
The term initialism uses a similar method,
but the word is pronounced letter by
letter.

7. INITIALISM
Initialism can refer to any abbreviation
composed of initials, even if pronounced as
a word; conversely, acronym has been
widely adopted to refer to any such
abbreviation, even if it is pronounced letter
by letter.
Distinction:
•True Acronyms are pronounced as words
•Pure Initialisms are said letter by letter

8. EMOTICON/EMOJI
When people communicate face to face, they
rely on facial expressions to enhance the
meaning of what the other person is saying.
Therefore, when you email or text someone,
it is hard to get your meaning across with
just words.
Then came the birth of emoticons.
