You are watching: We will cross that bridge when we come to it


For the idiom "We will cross that bridge when we concerned it", shouldn"t it be "We will cross that bridge once we will come to it"? If not, please help me understand how the last is grammatically incorrect.

In "We will cross that bridge once we involved it", "come" is the simple present tense offered to indicate the current in the future.

It is extremely common:

"John leaves in an hour, do not let him forobtain his coat."

In "when we involved it", when = at the time that, i.e. the present tense is supplied to develop the current at that time.

The simple answer is that generally, the word "will" isn"t supplied after "if", "when", or similar words.

Examples:

Incorrect: When the sun will certainly climb, I will certainly get out of bed.Correct: When the sun rises, I will obtain out of bed.

Incorrect: If you will check out David tomorrow, say hello to him for me.Correct: If you check out David tomorrow, say hello to him for me.

The idiom in the title of the question is correct.

From Merriam-Webster"s meaning of cross that bridge when one involves it:

: to not worry around a feasible difficulty until it actually happens// I do not know exactly how we"ll pay the bills if you quit your task, however we"ll cross that bridge when we come to it.

Consider the adhering to variations via just when or will:

When we come to that at some point, we will cross it.✔ We will concerned that bridge at some suggest.

And also the following variations via both words:

✔ We don"t recognize when we will come to that bridge.✔ When we will involved that bridge is unrecognized.

However:

When we will pertained to that bridge at some point, we will cross it.

It"s this certain combination of when and also will that is unnatural.

It seems that making use of when with will just forms an acceptable sentence if it"s then followed by just a verbal phrase or just a verb and an adjective.

But utilizing the combination in a dependent clause that introduces an independent clause is not idiomatic. Unfortunately, I do not recognize precisely why this would be, and I can"t put the factor behind it into an actual rule.

However before, I execute recognize which version of the sentence is idiomatic and which isn"t:

✔ We will cross that bridge when we pertained to it.✘ We will cross that bridge once we will concerned it.
