Coordinating Conjunctions

Use y to add similar ideas, and switch to e before words beginning with /i/ or /hi/ sound to maintain the sound flow.

Use o to present alternatives, and change to u before words that start with /o/ sound to avoid doubling the vowel sound.

Use pero to introduce a contrast or exception, and it appears between two clauses when the second idea qualifies or opposes the first.

Use sino to correct a negative statement with a contrasting noun or phrase, and use sino que when the correction introduces a new clause with a verb.

Use ni to join two or more negative alternatives, and it can start a phrase or clause that continues the negation.

Use también to add an affirmative idea that aligns with a previous one, and it typically appears before the verb or at the start of the added sentence.

Use tampoco to add a negative idea that matches an earlier negation, and it often appears at the beginning of the clause for emphasis.

Use más que to introduce a preference, correction, or emphasis when contrasting two ideas, and it can link phrases or clauses.

Coordinating conjunctions like y, o, pero, sino, and ni signal addition, choice, and contrast at the same grammatical level, while small changes like e/y and u/o help the sentence flow smoothly.
