Noun and な adjective
かんりょうてき
この会社では官僚的な形式主義がまかり通りすぎている。
There’s too much bureaucratic red tape in this company.
If 官僚 is "bureaucracy," then adding a 的 to it would make it bureaucratic.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Knowing 官僚 will help a lot too.
