Where English and Spanish really part ways.

Spanish has a family of verbs where the EXPERIENCER is the indirect object, not the subject — the thing experienced is the subject.

Many Spanish verbs add 'se' to mean something different from their non-reflexive form — the 'se' isn't 'oneself', it changes the meaning.

Spanish uses 'se' + verb to express both impersonal ('one X-es') and passive ('X is done') constructions where English uses different structures.

Spanish softens blame for small accidents by making the object the grammatical subject — the thing happens TO you, not by you.

Some adjectives mean different things depending on whether they appear with 'ser' or 'estar'.

The morphological future tense in Spanish often expresses SPECULATION about the present, not actual future.

The conditional ('podría', 'querría', 'gustaría') is the standard polite-request register — softer than the present tense.

When you describe something hypothetical or sought-but-not-found, the relative clause takes subjunctive.

Spanish uses 'tener + noun' for many physical/emotional states where English uses 'to be + adjective'.

Where English needs ONE negative, Spanish requires TWO — and the result still means the negative.

Spanish conjugation encodes the person; subject pronouns are usually DROPPED, kept only for emphasis or contrast.

Most adjectives go AFTER the noun in Spanish. A handful change meaning when placed before vs after.

Spanish puts 'a' before a direct object when it refers to a specific person — a preposition with no English equivalent.

Where English says 'I wash MY hands', Spanish says 'I wash THE hands to myself' — definite article + reflexive pronoun, not the possessive.

When both an indirect and direct object pronoun appear together, IO goes BEFORE DO. And le/les + lo/la/los/las collapses to 'se'.
