Maybe I am illiterate but I have just completed an internet check in on SQ and received an automated email. The email says "However, Singapore Airlines may have to re-assign seats without prior notice due to operational exigencies"
I am native English speaking and not specially stupid and yet have never come across the word "exigencies" before.
Is it wise to use such an uncommon word where any of the following could have worked just as easily.
crisis, contingency, plight, reasons
I expect it is a well educated Singaporean lawyer showing off his/her education, or before anyone else says it I am stupid.
