Therefore
Consequently
conjunction
With 故 meaning "reason" if you head towards that reason, you transition towards it. To say that in words, you might say therefore or consequently. You stated your case and ideas, then in order to go towards reason we use these words to transition towards it.
By knowing the word 故 you'll know the reading for this word too! Here's a mnemonic in case you need a reminder, though:
You're using WaniKani, therefore you're studying kanji and vocab. Whose fault is it? It's WaniKani's fault! But, your brain has been beaten to a mush from all the studying, so when you say "it's your fault" it comes out as "it's yue fault!" Go ahead and say it out loud that way.

I was repeatedly late without permission and consequently my vacation days were cut short.
