In mathematical logic, a sentence (or closed formula) [1] of a predicate logic is a Boolean-valued well-formed formula with no free variables.A sentence can be viewed as expressing a proposition, something that must be true or false.
Formulas themselves are syntactic objects. They are given meanings by interpretations. For example, in a propositional formula, each propositional variable may be interpreted as a concrete proposition, so that the overall formula expresses a relationship between these propositions.
In logic and analytic philosophy, an atomic sentence is a type of declarative sentence which is either true or false (may also be referred to as a proposition, statement or truthbearer) and which cannot be broken down into other simpler sentences.
Let ψ be a sentence in first-order logic.The spectrum of ψ is the set of natural numbers n such that there is a finite model for ψ with n elements.. If the vocabulary for ψ consists only of relational symbols, then ψ can be regarded as a sentence in existential second-order logic (ESOL) quantified over the relations, over the empty vocabulary.
Pathetic fallacy (also known as anthropomorphic fallacy or anthropomorphization) is a specific type [dubious – discuss] of reification. Just as reification is the attribution of concrete characteristics to an abstract idea, a pathetic fallacy is committed when those characteristics are specifically human characteristics, especially thoughts or feelings.

Using a complex sentence is a way to refer to the content of the paragraph above (dependent clause) and then bring in the content of the new paragraph (the independent clause).
