Usage Rules

When using Spanish words that start with “o,” it is important to follow the grammatical rules of the language.

Verbs must be conjugated correctly to reflect the tense, mood, and person. Adverbs should be placed appropriately in the sentence to modify the intended word or phrase. Pay close attention to these rules to ensure accuracy and clarity in your Spanish communication.

A key aspect of Spanish grammar is noun-adjective agreement. This means that the gender (masculine or feminine) and number (singular or plural) of an adjective must match the noun it describes. For example:

• El ojo azul (The blue eye – masculine singular)
• La casa oscura (The dark house – feminine singular)
• Los ojos azules (The blue eyes – masculine plural)
• Las casas oscuras (The dark houses – feminine plural)

Verbs in Spanish have different conjugations depending on the tense, mood, and subject. For example, the verb obedecer (to obey) is conjugated as follows in the present tense:

• Yo obedezco (I obey)
• Tú obedeces (You obey)
• Él/Ella/Usted obedece (He/She/You obey)
• Nosotros obedecemos (We obey)
• Vosotros obedecéis (You all obey)
• Ellos/Ellas/Ustedes obedecen (They/You all obey)

Common Mistakes

A common mistake is using the wrong gender for nouns. For example, saying “el olla” instead of “la olla” is incorrect. Another mistake is not conjugating verbs correctly. For instance, saying “Yo obedecer” instead of “Yo obedezco” is a grammatical error. Additionally, forgetting to make adjectives agree with nouns in gender and number is a frequent mistake. For example, saying “la ojo azul” instead of “el ojo azul” is incorrect.

Here are some pairs of incorrect and corrected sentences:

Incorrect Sentence	Corrected Sentence
El olla está caliente.	La olla está caliente.
