Chtěl bych koupit své ženě dárek?
Yup. We had 1009 versions of this sentence before I incorporated your suggestion in all versions. Now we have 1729. One little suggestion for a man, one huge step for Duolingo..
And today, we have 1969 versions. And I'm sure some possible solutions are still missing. :-p
Works as well. :)
Chtěl bych koupit své ženě dárek. - emphasis on dárek
Chtěl bych koupit dárek pro svoji manželku. - emphasis on svoji manželku
You usually put the information that you want to stress at the end.
