Caerphilly County Borough Council has 664 staff who can speak two or more languages, a recent survey has found.
Out of the multi-linguists, half are Welsh speakers, according to the local authority.
As well as Welsh, the council’s survey found that a total of 26 different languages were spoken by its employees.
These included French, British Sign Language, German, Spanish, Italian and Kurdish.
Cllr Allan Pritchard, deputy leader and cabinet member for human resources, said: “I am delighted that we are such a culturally diverse workforce and have such a wide variety of languages at our disposal for the benefit of our residents.
“Although we actively encourage residents to correspond with us primarily in either English or Welsh, our residents are well within their rights to communicate with us in the language of their choice.
“It is excellent that we have staff in our own organisation who are able to verbally translate information about council services such as recycling and waste, leisure and community facilities and benefits in a variety of languages should the need arise.”
