sic – Template
The Latin adverb sic ("thus"; in full: sic erat scriptum, "thus was it written") added immediately after a quoted word or phrase (or a longer piece of text), indicates that the quotation has been transcribed exactly as found in the original source, complete with any erroneous or archaic spelling or other nonstandard presentation. - Wikipedia
Or in other words: Use to denote that what looks like a spelling or grammar mistake, is in fact, not.
Usage
{{sic}} placed immediately after a circumstantially correct but unusual spelling or grammatically iffy statement, will add a small but superior note at that point in the text, that links to Category:Sic Erat Scriptum, whilst simultaneously adding the page to that Category.
Example
If we have a sentence containing:
"...so we can then use setDammage to..."
We can add this template like so:
"...so we can then use setDammage{{sic}} to..."
which will produce:
"...so we can then use setDammage[sic] to..."
Alternatively we may highlight the sic statement thus:
"...so we can then use {{sic|setDammage}} to..."
which will produce:
"...so we can then use setDammage[sic] to..."
