💡 Grammar Points
The 'A' Connector
When describing what something smells like, Spanish uses the preposition 'a' (to/at): 'Huele a lavanda' (It smells like lavender).
The H-Addition (Irregularity)
In the present tenses (like 'yo,' 'tú,' 'él/ella,' 'ellos/ellas'), the verb changes from 'o' to 'ue' and adds an 'h' at the beginning: 'huelo' (I smell). This 'h' is silent!
❌ Common Pitfalls
Forgetting the 'H'
Mistake: "Using 'uelo' instead of 'huelo'."
Correction: Always remember the silent 'h' in the stressed forms: 'huelo.' It's a special spelling rule for this verb.
⭐ Usage Tips
Telling vs. Doing
This meaning (Definition 1) is often used impersonally ('Huele bien') to describe the quality of the smell, not the action of smelling.

"Oler" can mean "to sniff," the action of actively using your nose to detect something.
oler(verb)
to sniff
?using your nose to detect a scent
,to smell (an object)
?the active process of smelling something
to scent

💡 Grammar Points
Direct Object
In this meaning, 'oler' takes a direct object (the thing you are smelling): 'Oler la sopa' (to smell the soup).
⭐ Usage Tips
Action vs. Perception
If you are actively using your nose, use this meaning. If you are just noticing a smell passively, use Definition 1.

This figurative use is often paired with 'mal' or used with the preposition 'a' to indicate what the situation resembles (e.g., 'huele a trampa' - it smells like a trap).

Frequently Asked Questions
Why does 'oler' start with a silent 'h' in some forms but not others?
This is a special spelling rule! The verb stem changes from 'o' to 'ue' in stressed forms (like *huelo*). Spanish spelling rules require adding a silent 'h' at the beginning of a word if it starts with the sound 'ue' (like *huevo* or *hielo*). This ensures the vowel sound is clear.
How do I know if 'oler' means 'to perceive a smell' or 'to sniff'?
If it is used with the preposition 'a' ('huele a café'), it usually means the passive perception (Definition 1). If it takes a direct object and describes an action performed by a person or animal ('olimos el perfume'), it means active sniffing (Definition 2).
