ToBE #28: Ad-hoc oppurtunity aganist temporavary caluculation

To start with, all words in the title are wrong, each it its own way.

Ad-hoc:

• Not "ad-hoc", not "adhoc". It is always two words - "ad hoc".
• It does not mean 'random', 'unplanned' or 'unstructured', though most of us tend to use it that way. It means, "For the (specific) purpose". When an ad hoc committee is formed, it is formed for a specific purpose, not in an unplanned manner. When you want to describe a set of processes as unstructured, the next time, please don't use "ad hoc".
• Of late, a new usage creep is happening: Ad hocism. Such a phrase does not exist and is best avoided.

Oppurtunity:
A common misspelling pointed out by one of our regular readers. The word is "opportunity".

Aganist:
Another common mistake made by people from a certain part of India. The word is "Against".

Temporavary:
A common mistake from another part of India. This sounds like some kind of tax like "varumAna vari" (income tax), "viRpanai vari" (sales tax). There is no "va". It is "temporary", not "temporavary".

Caluculation:
A common mispronunciation by some people is including a 'u' sound after 'Cal'. It is "Calculation", not "Caluculation".
