At Once
Right Now, Immediately, Right Away
adverb
You'll have to learn this word in two parts. You already know the meaning of 今 because of the kanji, which means "now." The すぐ part, however, is a new word, meaning "soon." すぐ and "soon" even start with a similar sound, so maybe that can help you remember this! If you put 今 and すぐ together, you get "now soon." Put in better English, that's at once or right now.
Since you already know the vocab word 今 (read いま), you should be able to read this word as well.
