Kert Kask, an expert in Estonian spelling, is helping prepare participants for an e-dictation event taking place on March 13. He emphasizes the importance of correct spelling in Estonian, particularly explaining why the word "mõttetu"—meaning "meaningless"—should be spelled with two 't's. According to Kask, the suffix '-tu' is added to the genitive form of the word 'mõte', which is 'mõtte', leading to the correct spelling 'mõttetu'.

This explanation highlights a common confusion in the Estonian language where the nominative and genitive forms of certain words can appear similar. Kask points out that understanding the grammatical structure is crucial for correct spelling, especially in the context of the upcoming e-dictation event hosted by Vikerraadio on Mother Language Day.

The e-dictation event is set to take place at 10:25 AM, allowing people to engage with the Estonian language in a fun and educational way. Kask's insights not only help to clarify specific spelling rules but also emphasize the broader importance of correct language use in maintaining the integrity of the Estonian language.
