";" Semicolon is a punctuation mark between comma and period in hierarchical structure, which is mainly used to separate two clauses with certain relationship (juxtaposition, turning, undertaking, cause and effect, etc.). )-Clauses can belong to a single repetitive sentence, or they can be the first-level clauses of multiple complex sentences, or they can be the juxtaposed parts of big sentences.

In addition, semicolons can also be used to separate parallel phrases that appear as enumerations, or different interpretations of the same meaning in dictionaries. See the text for details and examples. In addition, "semicolon" can also mean "branch"

explain

One or both clauses in examples (1) (2) and (3) contain commas, so the clauses are separated by semicolons. The clauses in Examples (4) and (5) do not contain commas. The use of semicolons between two clauses in Example (4) is a general usage, and the use of semicolons in Example (5) is a special usage, which emphasizes the relative independence of two clauses in a whole.

In English, two parallel clauses that are not connected by conjunctions as in Example (4) cannot be separated by commas, but must be separated by semicolons as in Example (5).
