yes, single crochet is the term that americans use for double crochet, most american books have a conversion chart for british crochet but just checked and Mr Funky doesnt! The easiest way I’ve found to tell if youve got an american pattern is to check the instructions, if it says gauge then its american, if it says tension its British. There is a crochet conversion chart in whisper (simply knitting) but might be one in LK too. If not then they should print one!!! Sounds like we’re in the same book club!
