Even though it ends in '-es', remember that 'bases' is the plural of 'la base' (feminine), so you must use feminine articles and adjectives with it (e.g., 'las bases fuertes').

Always Feminine Plural

Use 'bases' when talking about abstract foundations (like ideas or rules) and also for physical bases (like in baseball or a military camp).

Abstract vs. Physical

Extremely common. Used daily in academic, professional, and casual contexts to mean foundation or principles.

Mixing Command Forms

This form ('bases') is used when expressing doubt, wishes, emotions, or necessity in the second part of a sentence, especially after phrases like 'Quiero que...' or 'Es importante que...'

The Subjunctive Use

To tell someone (informally, 'tú') *not* to do something, you must use the present subjunctive form. The negative command for 'basar' is 'No bases'.

Negative Commands

For regular verbs ending in -ar like 'basar', the subjunctive endings switch to 'e'. This is why 'tú basAs' (indicative) becomes 'tú basEs' (subjunctive).

Remember the 'E'

Moderately common. This specific form is used when talking about actions that are uncertain, desired, or commanded.

Learn the Spanish word 'bases', covering its primary use as the plural noun meaning 'foundations' or 'principles', and its use as the present subjunctive verb form of 'basar' (to base). Includes examples and conjugation.
