Sermonspeaker language override

Hi
how to create sermonspeaker language overrides, because after component update i lost my translation. Thanks

Either create them in the Joomla Language Manager or create the respective files in the global language directory.
See docs.joomla.org/J3.x:Language_Overrides_in_Joomla

I saw this, but do not understand. Have I to write all string from language file?

Only those you want to change.
If you prefer, you can also edit the override file directly. All the Override Manager does is creating and populating an INI file in the /language/overrides folder. There will be one INI file for each language you have changed something.

Can i copy file from
components/com_sermonspeaker/language/xx-XX/xx-XX.com_sermonspeaker.ini
and put it in /language/overrides/xx-XX.com_sermonspeaker.ini folder?

Solved.
/language/overrides/xx-XX.override.ini
