English Grammar Rules & Mistakes: Learn All of the Essentials: Writing, Speaking, Literature and Punctuation Rules Complete with 10 Key Skills and Over 200 Common Error Examples

GRAMMAR COMPONENTS AND WORDS
As English language learners, there are basic and complex English grammar
errors made when communicating. To joggle your memory a bit, language
use refers to your ability to effectively comprehend (when spoken or written
to), and produce (communicate) both spoken and written words. So the
understanding of how the English language works is confined in thorough
appropriation of English grammar rules which the English language lives by.
As described in chapter one, there are basic English grammar rules to abide
by in order to communicate well. Any attempt to do otherwise would lead to
a colossal grammatical error. In the same instance, other complex English
grammar components and words also have specific rules to pay due respect to
when being used, be it formally or informally. All said, let us go through the
components and words.
Abbreviations
In a short sentence, an abbreviation (abbr.) is a chunk of lengthy phrases or
words. As a user of the English language, you can use an abbreviation when
you need to reduce a large number of words in a sentence to a single reduced
sequence of letters, or to chunk an extensively long sentence into fewer
letters to make your statement/sentence more interesting to read. For
example, if you have to use North Atlantic Treaty Organization for every
place you need to simply use NATO (an abbreviation), you’ll realize how
boring your writing can be to your audience. A more important fact
associated with abbreviations is that they make communication easy for us. in
this case, you don’t have to write or speak every word for every statement
you mean. For example, “I am the CEO/CFO/MD of that company” looks
cool right?
To clarify the concept of abbreviation; there are forms of abbreviation which
are called acronym and initialism. An acronym is derived from the initial
letters of a long word or phrase. When National Aeronautic Space
Administration is reduced to NASA, it’s simply an acronym. In an acronym,
you do not pronounce the acronym letter for letter; rather, you take it as a
single word.

NB. Acronyms are pronounced as a word, e.g., NATO (nay tow), NASA (na
sa).
Initialism is another version or form of abbreviation and it is derived when a
phrase is reduced to initial letters. In this regard, initialized words are
pronounced as individual letters. When you reduce National Football
Academy to NFA, initialism is at work. Hence, initialized words are taken
letter for letter.
NB. Initialisms are pronounced letter for letter, e.g., Personal Computer PC
(peecee), NFA (en ef ay) Alternative Dispute Resolution (ay dee ar).
Whether you initialize or use acronym, abbreviating words can be erroneous
if you do not acclimatize yourself to them.
Now that you know what abbreviation means and the varieties of
abbreviation in English grammar, let’s go through common abbreviations and
rules that need to be taken care of in order to avoid unnecessary errors.
You can abbreviate a word by omitting one or more syllables.
examination 
exam
memorandum 
memo
decapitation 
decap
recapitulate 
recap
advertisement 
advert
In the case of names, you can also omit one or more syllables.

Use cases of common written sentential abbreviations, pay attention to the
following:
If in a sentence you mean to say for example, simply use e.g. E.g. is
initialized from the Latin phrase exempli gratia, which in English is
translated as for example.

---

Also, do not confuse e.g. with i.e.
So e.g. means for example, and it is used for sentence clarification by giving
instances. I.e. is from the Latin phrase id est, which translates to that is or
