 To _aggregate_ [data][data] [grouped by][grouped by] an [ID][id] over a [function][functions] we can use the aggregation expression:
 
 ```ttsl

 Let's break down the syntax:
 
 - The keyword `#!ttsl aggregate`.
 - The [function][functions] to be executed on the grouped values (here `#!ttsl sum`).
 - The keyword `#!ttsl of`.
-- A [List][List] of [data][data] separated by a comma (here `#!ttsl salery, taxes`).
+- The [data][data] that is aggregated (here `#!ttsl taxes`).
 - The [grouped by][grouped by] modifier (here with the id `#!ttsl hh_id`).
 
 An aggregation can be executed on one or multiple data values that are all connected to the same given [ID][id].
