German and French, also ancient languages.
My ex-wife is a professional linguist in German. Though my German suffers from not having studied it at school, I have since done courses  and spent a considerable amount of time on and off  in Germany - at a social level I can cope.  French I did study at school for eight years (grade A at A' Level) and I have used it on holidays. The University of Cambridge entrance examination in 1968 required me to sit papers in two languages and I offered French and Latin, both of which were accepted as satisfactory. I also have Grade 1 in O’ Level Ancient Greek (and have visited Greece). I have attended several international workshops/congresses.
