which conjunction word would best combine the two sentences together. then or until. i would prefer "until" is that ok

For centuries people ate with their hands. A change finally occured in the 1100's when people used utensils.

I agree. Until is best.

thank u Ms. Sue

oh one more thing. i should use a comma right before until

Yes... a comma.... Until would begin an adverb clause modifing the verb.

For centuries people ate with their hands. A change finally occurred in the 1100's when people used utensils.

To combine the two sentences using the conjunction word "until," you can rephrase them as follows:

"For centuries, people ate with their hands until a change finally occurred in the 1100's when people started using utensils."

In this sentence, "until" is used to indicate the period of time during which people ate with their hands and the point at which the change to using utensils occurred.

It doesn't make sense when we say dial a telephone number. Push buttons are used now.
