Questions & Answers about Sans doute la sonde a-t-elle analysé l'atmosphère.

Why is it la sonde a-t-elle instead of just la sonde a?

This is a complex inversion, which is highly recommended in written French when you start a sentence with certain adverbs like Sans doute, Peut-être, or À peine. Because the subject la sonde is a noun rather than a pronoun, it stays in its normal place before the verb, and we add the matching pronoun elle after the verb to create the inversion.

What is the purpose of the -t- in a-t-elle?

It is added strictly to make the pronunciation smoother. When you invert a verb and a pronoun, and the verb ends in a vowel like the auxiliary a while the pronoun begins with a vowel like elle or il, you must insert a -t- with hyphens to prevent the two vowel sounds from clashing.

Doesn't Sans doute literally mean without a doubt? Why is it translated here as probably?

It is a classic false friend! Over time, sans doute lost its absolute certainty in French and now usually translates to probably or likely. If you want to express complete certainty like without a doubt or undoubtedly, you must use sans aucun doute.

Is there a way to say this without using the tricky complex inversion?
