Verb conjugation of "verachten" in German

My boss offered it to me, so that a few more people at work will have a good level of English and now I really have to kick my own ass (I've started last year and it's not going very well).
My name is Wolfgang, and I am interested to build my Spanish vocabulary. Maybe we can practice together. How long have you learned Spanish? I have been learning for a few years with books.
First, let me thank you for your answer. And how can I support you further? I'd be very happy about it if we could both help in each other in learning Spanish. 'Tandem' learning beats all other methods.
