"Fight for truth, whole truth & nothin but! The sentence can have one reading or more. Let's investigate it.

Grammatical Level

On the grammatical level, to start with, it is a compound complex declarative sentence made of three independent clauses. In English grammar, compound-complex declarative sentences are sentences with two or more independent clauses and one or more subordinate clauses. They follow the rules for both compound sentences and complex sentences.

Three independent clauses declaring a decision to make, a statement, or an explanation to give. "Fight for truth", whole truth", "nothing but!". The declaration given here is to "fight for truth" as the author stated. In a compound complex declarative sentence, clauses are generally separated by either a comma paired with a coordinating conjunction or a semicolon. But what is a declarative sentence? A declarative sentence is a sentence that makes a statement to convey information, states facts, offers opinions, or provides explanations. A declarative sentence is used when someone wants to express a fact, give some information, or explain something. Any time you state a fact, an opinion, observation, or explanation in a plain manner, you are using a declarative sentence and lets the reader know something specific. It always ends with a period. The example above is different. Let's have a look on it.

We have learnt at school that there are three main types of ending punctuation in English language: the period (.), the question mark (?), and the exclamation mark (!). A period (.) is the punctuation mark that indicates the end of a sentence. The question mark (?) replaces a period at the end of a sentence that asks a direct question. The exclamation mark (!) is a punctuation mark usually used after an interjection or exclamation to indicate strong feelings or high volume (shouting), and often marks the end of a sentence. Being said, should we read the statement above as a declarative sentence or an imperative sentence? The exclamation mark in the example has changed the grammatical category of the sentence and thus change the readers' interpretations. We have mentioned in an earlier our previous post: words have power that readers are different. A text can have different readings. A dialogue between two entities or more, could be interpreted differently depending on - as stated - the encoder, decoder, transmission, environment, gender, cultural background and other things.

Morphological level

On the morphological level, the sentence contains incorrect terminologies or jargons. e.g., /nothing/ is typed incorrectly. According to Oxford English Dictionary, /nothin/ should be typed as /nothing/ with an unvoiced [g]. The case above could be explained as follow:

In linguistics, morphology is the study of words, how they are formed, and their relationship to other words in the same language.[2][3]. Morphology analyses the structure of words and parts of words such as stems, root words, prefixes, and suffixes.

Terminology

Nothing, no-thing, or no thing, is the complete absence of anything; the opposite of everything, or its complement. (https://en.wikipedia.org/wiki/Nothing). Nothing or The Nothing may also refer to: Zero, the mathematical concept of the quantity of things. The term has been written in different form in English. To mention some nothyng, noon thing, non thing, na þing, nan thing, nan þing, nāþing, nān þing , equivalent to no +‎ thing. Compare Old English nāwiht (“nothing”, literally “no thing”). Having seen that, we could say that the term was used in one of the cases listed below:

1 - 'nothin' was used here in a slang form:

According to the free dictionary, the term 'nothing but' means 'the exclusion of all else': 'Jane drinks nothing but milk'

A large quantity of or exclusively (the thing that has just been inquired about). Typically used hyperbolically. A: "Do you have any extra pens?" B: "Nothing but! Take your pick."

2 - the author was listening to 'nothin' musical band

The author could have typed the statement while they were listening to the song ‘nothin’ a song written by and sang by. The song contains some strong and thus might have an impact on the author’s style,

3 - 'nothin' was typed wrongly to leave us confused

The author could in another reading typed the term wrongly. This could be done intentionally to leave us in a state of confusion.

Semantic Level

On the semantic level, the sentence could have two readings ‘Fight for truth, whole truth & nothin but! Could mean,
