You know how 経 means passage of time, right? Well, this is the verb form of that. What does time do when it passages? It passes. So, this verb means to pass or to elapse.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: What do you say to time as it begins to pass you by? "Ta ta (た), Time!"
