I bought this book ages ago as it was the required material for the EES hieroglyphics course, so I thought a good enough recommendation.
It is pretty accessible and does a nice gradual slide into more increasing complexity. The objective though is to help with monument reading which has some limited scope for other stuff. Mind you, while I don’t have a great head for languages and much of what I’ve read has been forgotten, some bits have stuck such as the markers for ‘Something said by…’ etc.
Has a number of useful transliterated words which have proved useful.
