Ablative and Accusative

Familia Romana: CAP IV: Davus sacculum in mensā pōnit (Ablative)
CAP IX: Pastor laetus ovem in umerōs impōnit (Accusative)

For in + accusative would require some “movement”. If so, would my translation meet that requirement? The shepherd picks up the sheep from the ground and places it on his shoulders.

Or am I barking up the wrong tree altogether?

Latine Disco: Chap 5: The prepositions ab, cum ex, in, sine are said to “take” the ablative.

Do you see that your first example is ponit and the second is imponit?

Do you know the normal difference between in plus ablative and in plus accusative? The first is “on” and the second is “into”.

The water is muddied here because of the prefix “im” of the verb ponit. So impono takes an accusative with in.

You have rather over translated the sentence.

Thanks seneca. Yes, I did see the difference between ponit and imponit and know the difference between in plus ablative and in plus accusative. So, since in plus impono takes accusative there’s no need to look for “movement” and no need to tie myself in knots. Unfortunately that wasn’t made clear in Lingua Latina. Again many thanks for your usual helpful and welcome advice!
