juntas
HOON-tasˈxuntas

Matching the Group
When using 'juntas' to mean 'together,' remember the ending must match the group. If the group has at least one male or mixed genders, you must use the masculine plural form: 'juntos'.
Adverb vs. Adjective
This word often acts like an adverb (explaining how an action is done: 'trabajar juntas'), but it can also be an adjective (describing a noun: 'mesas juntas').
Gender Misuse
Mistake: “Mis amigos y yo vivimos juntas.”
Correction: Mis amigos y yo vivimos juntos. (Use 'juntos' because the group includes males/mixed genders.)
conjuntamente
kon-hoon-tah-MEN-tehkonxuntaˈmente

The '-mente' Rule
In Spanish, adding '-mente' to the end of a feminine adjective is like adding '-ly' in English. It tells you how an action is being done.
Word Placement
You can place this word after the action verb (e.g., 'trabajamos conjuntamente') to emphasize the way you are working.
Using 'conjuntamente' when you mean 'juntos'
Mistake: “Mis amigos y yo fuimos conjuntamente al cine.”
Correction: Mis amigos y yo fuimos juntos al cine. (Use 'juntos' for simple social activities; 'conjuntamente' sounds very professional or formal, like a business merger!)
