French Apr 10, 2015 #15 Thank you for your advice Perpend. my sentence (even though I don't truly understand the meaning here) is "I like exploring new areas. Things I never imagined I'2r take any interset in. Things that make you go hmmm."

Folgende Sachen dieses Abschnitts scheinen seit dem zeitpunkt 200x nicht eine größere anzahl aktuell nach sein: An dieser stelle fehlen 20 Jahre Geschichte, die Überschrift ist unpassend Litanei hilf uns dabei, die fehlenden Informationen zu recherchieren außerdem einzufügen.

Actually, they keep using these two words just like this all the time. Rein one and the same Liedtext they use "at a lesson" and "hinein class" and my students are quite confused about it.

Rein an attempt to paraphrase, I'durchmesser eines kreises pop in a "wow": I like exploring new areas. Things I never imagined I'd take any interest rein. Things that make you go "wow".

In your added context, this "hmmm" means to me more of an Ausprägung of being impressed, and not so much about thinking about something. There is of course a fine line.

As I always do I came to my favourite Gremium to find out the meaning of "dig rein the dancing queen" website and I found this thread:

But what if it's not a series of lessons—just regular online Spanish one-to-one lessons you buy from some teacher; could be one lesson (a trial lesson), could be a pack of lessons, but not a part of any course.

Here's an example of give a class, from the Medau News. I think the expression is more common in teaching which involves practical physical performance, like dance or acting, than in everyday teaching in a school.

There are other verbs which can be followed by the -ing form or the to +inf form with no effective difference in meaning. Teich this page (englishpage.net):

I an dem closing this thread. If you have a particular sentence hinein mind, and you wonder what form to use, you are welcome to start a thread to ask about it.

I could equally say I have a Spanish lesson tonight, and this is one of the lessons that make up the class I'm attending this year. It's also possible for my class to be one-to-one. Just me and the teacher.
