Surely you have already heard and used the terms land or land to refer to the act of descending and landing somewhere. As both forms are commonly used, both in speech and in writing, it is normal for doubt to exist, as they have different spellings and pronunciations, despite having the same meaning.
Well, what you shouldn't know is that both forms exist and are dictionized, that is, both are admitted in the written modality. However, the form “land”, with ss, is better accepted in the standard norm and has its use advocated by linguists, which does not prevent us from using the form “land” with z. Look at the examples:
The plane will land safely despite the turbulence during the flight.
The plane will land safely despite the turbulence during the flight.
the lunar probe landed on the moon successfully.
The lunar probe has successfully landed on the moon.
The verb to land is formed from the word to land, so it must be written with the digraph ss. The verb to land is formed from prefixal and suffixal derivation, when prefix and suffix are added to an already existing word, giving rise to another. Watch:
a- + earth + -izar
The verbs to land and to land are synonymous with the verb “to land”, which can be used in the same linguistic situations, although it is not commonly used. As for the nouns of verbs, there are also forms, landing, landing and landing. Despite the existence of the three nouns,it is worth noting that the noun landing is more used.
