My dictionary tells me that kental means "curdled". But how about this wording in the Media Permata (16 April, 2009, p. 40):
Frank Lampard memuji semangat kental ChelseaNow, the spirit of Chelsea was splendid, invigorating, and heroic in managing to overcome the challenge of Liverpool and thereby progress to the semi-finals of the Champions League. But curdled?
"Frank Lampard praised spirit ????? Chelsea"
It seems that, in the context of semangat, kental means "strong-willed" rather than curdled.
Anyway, let's all celebrate a fine match and a splendid result for Chelsea.
