Meaning
To be involved in or aware of a secret or clandestine matter.
Cultural Background
Garlic is the 'holy trinity' of Spanish cooking along with olive oil and onion. Using it in an idiom shows how deeply food culture permeates language. While understood, Mexicans might more frequently use 'estar al tanto' or 'estar en la jugada', but 'estar en el ajo' remains a classic literary and film import. In the Rioplatense region, 'estar en la pomada' is a very strong competitor for this expression. The concept of 'el secretismo' (secrecy) and 'el chisme' (gossip) is a major social driver in many Spanish-speaking communities, making this idiom very high-utility.
Use with 'de'
Always follow with 'de' if you want to specify the secret: 'Estar en el ajo de la operación'.
Not for formal emails
Avoid using this in a formal email to your boss unless you have a very close relationship.
