Copy the custom eb language file to Override folder?

I have customised the language file for eventbooking. In order not to lose my changes when I update eb,  should I need to keep the original eventbooking language file in the main en_GB file and place the customized file inside the override folder?
Thank you,

Hello

No, you do not need to override the language file. Your change will be kept when you update to future releases of Events Booking, don't worry
