Answer 1

Absolute file system path and file name of a .csv file that contains the combined translation dictionary and meta-information necessary for breakdown into a language package.

Use bin/magento i18n:collect-phrases to create the .csv file then create the language package as discussed in Create directories and files.

-m --mode If a target file already exists, specifies whether to replace the existing language package or merge with the new language pack. Merging overrides any phrases that existed and adds new ones.

Values: merge or replace (default).
