What is "in-situ" phenomena. I have a vague recollection of perhaps knowing something about the meaning of this term, but alas last week is much too far away and I've already forgotten large chunks I've what I learnt in my weeklong cursory overview of syntax (is "cursory overview" perhaps a tad redundant, it seems to me that by definition any overview is cursory. Anyways, I think I added "cursory" to emphasize my displeasure with most of my linguistics course. Were that it weren't so.)
