The lexical meaning of the word 'felicitation' is congratulation. So far I have known that a person superior in rank felicitates if his junior has achieved any feat but kindly tell me can the word 'felicitate' be used by juniors if they are congratulating their seniors. Let me illustrate my point with an example. our Principal has been conferred upon presidential award and all the teachers have organised a programme for her for achieving this feat. Can we call it 'felicitation ceremony' or celebration of ma'am's success.
