Remarks: 1.1.1. When this rule applies to the propositions, it is equivalent to the rule that stipulates that semicolon is used to separate propositions that coma used. For more information see this site: Cyrus zocdoc. Remember that the rule only applies to coordinated propositions, or in series; not to subordinate CAs. 1.1.2 Complex series must be separated with semi-colon although the latter two constituents are linked by conjunction, as you can see in the last three annotated examples. However, you can use a comma instead of semicolons, before the conjunction of the last constituent in the series: in a relationship whose elements are separated by a comma, the last element, before which appears the old combination, will be preceded by comma or semicolon.

With great aplomb, said his family would come to all three; to his friends, who expect at five; and managed to be punctual in both cases (RAE, spelling, 1999, p.) (59). 1.1.3. When similar items are separated by commas, you must use this sign for them all; the same should be if the semicolon is used. The use of the comma and semicolon must never toggle to separate similar elements, with the exception of the case in which you prefer using comma before the conjunction that tops the last element. Examples: It was beautiful, singing birds, the field looked forward and environment charged movement and freshness. It was beautiful; singing birds; the field was glad; and the environment charged movement and freshness.
It was beautiful; singing birds; the field looked forward, and the environment charged movement and freshness. 1.2. Before of some conjunctions in propositions where propositions are long long, semicolon can be used before some consecutive, adversative and causal conjunctions which are usually separated by commas. The semicolon is imperative when such conjunctions separated constituent complexes in which commas have been used.
