A Tamil gentleman nearly got clobbered when he appreciated the food served for lunch at his Telugu friend’s place.
The poor guy innocently said ‘Pramadham’ which means ‘Excellent’ in Tamil, but unfortunately means ‘Danger’ in Telugu!
‘Tamasha’ means ‘light stuff’, ‘Comedy’ etc in Malayalam, but beware if you use it flippantly with the Hindi speaking people.
Indiscreet use of this word- which means a street dance or something in Hindi- is not received kindly by them.
The simple word ‘Avasar’- which also is a Sanskrit root word- means ‘Occasion’ in Hindi; ‘Avasaram’ means ‘Requirement’ in Telugu; ‘Opportunity’ in Malayalam and ‘Hurry’ in Tamil!
There must of course be several such examples in the various languages ‘spooken’ in our delightful India.
