在這里,這一句可以理解為倒裝,但其實(shí)它是一個(gè) there be 句型,有時(shí)為了理解的方便,我們常把 there be 句型理解為（時(shí)間或空間的）“有” ,如：
There is a tree in front of the house.= 房子前面有棵樹(shù)；
There are some words on the biackboard.= 黑板上有幾個(gè)字；
There was a meeting yesterday.= 昨天有個(gè)會(huì)議；
There were some meetings yesterday.= 昨天有好幾個(gè)會(huì)；
這樣,there was even a princess ...就可理解為：甚至有一位公主···；
...who gave him ...,是定語(yǔ)從句,限定修飾 a princess 的；
原句的意思是：甚至有一位公主不時(shí)地給他一點(diǎn)穿衣吃飯的錢.
