Another deep Tagalog word you'll find in textbooks but rarely hear at the 'palengke'. It literally means 'head of the nation' ('ulo' + 'bayan') and refers to the capital city, like Manila. If you use 'ulumbayan' in a sentence, people might think you're a history professor or a contestant in a 'Buwan ng Wika' contest. 'Kabisera' or just 'capital' is what we say.
