Lipogrammatic text

[Anton]

But your text will still look normal.

Some things may be altered, e.g. if in English we exclude the letter "e", then, a) the character relative frequency table will be altered (frequences measured relatively to the most frequent letter will change), b) bigram frequency table will change as well, notably there will be no "e_" (e plus space) no more. Grammar will be more restricted - e.g. insofar there would be no "were", plural past tense will diminish in occurrence, etc.
