Natural Stress Rules: Words ending in a vowel, n, or s naturally place the stress on the penultimate (second-to-last) syllable. Words ending in any other consonant naturally place the stress on the final syllable.
The Role of Accents: Written accents (tildes) are used to override natural stress rules. If a word has a written accent, that specific syllable must be emphasized regardless of the word's ending.
Syllabic Division: Understanding how to break words into 'beats' or syllables is the first step in applying stress rules correctly. For example, a four-syllable word requires identifying the correct 'beat' to emphasize for clarity.
Comparative vs. Superlative: Use a comparative when looking at exactly two items (Subject A vs. Subject B). Use a superlative when picking one item out of a larger group (The best subject in the whole school).
Agreement Priority: Always ensure the adjective agrees with the subject of the sentence, not the object of comparison. If you say 'The library is more modern than the classrooms,' 'modern' must be feminine singular to match 'library'.
Identify the Target: When asked to compare, look for the 'que' or 'como' keywords to determine which structure is required. Forgetting 'que' after 'más' is a frequent error that loses marks.
Check the Ending: Always double-check adjective endings. In a fast-paced exam, it is easy to forget to change a masculine adjective to feminine when describing a feminine subject like 'la asignatura'.
Listen for Stress: In listening exams, word stress can help distinguish between similar-sounding words or identify the intended meaning of a sentence.
False Friends: Be wary of words that look like English but have different meanings. For instance, 'suspender' in a school context often means 'to fail' an exam, not 'to suspend' a student.
Over-regularization: Students often try to say 'más bueno' or 'más malo'. Remember to use the irregular forms mejor and peor instead.
Missing Articles: In superlatives, the definite article (el/la/los/las) is mandatory. Saying 'más divertida asignatura' instead of 'la asignatura más divertida' is grammatically incomplete.
