A seller offers 'this heap of wheat for 10 dinarim' without specifying the measure. Is the sale valid?
When the species is identified (wheat), the sale is binding even without knowing the exact measure. The parties later settle any ona'ah based on market price.
Question 2
Someone says 'I sell you whatever is in this locked box.' The buyer performs meshichah. Is the sale valid?
Selling 'whatever is inside' without knowing the type is void — the buyer cannot form a settled intent when the contents could be straw or gold. It is tantamount to gambling.
Question 3
What are the standard dimensions when selling a place for a regular house (beit chatanus / beit almanut)?
A basic dwelling — whether a wedding home for a son or a widow's home for a daughter — is built 4 cubits wide by 6 cubits long, with height equal to half the sum of length and width.
Question 4
A seller draws three boundary lines but omits the fourth. The fourth border strip is not enclosed by the other three and has a row of date palms on it. What does the buyer acquire?
If the fourth boundary is not enclosed within the other three AND has a row of palms (or is large enough for nine kabbim), the buyer does not acquire it.
Question 5
A seller says 'I am selling you fields (שדות).' How many fields does the buyer minimally acquire?
The plural 'fields' implies the minimum plural — two fields. 'All my fields' would extend to three or four (excluding gardens and orchards); 'all my property' reaches even further.
