Back to informal language

In many cases, the TV Corpus is more informal than the Spoken portion of the BNC (British National Corpus) in terms of syntax (grammar).

Features #1-3 below are informal features of English syntax (click on the BNC link to see evidence of this). In nearly every case, these informal features are more common in the TV Corpus than in the Spoken section of the BNC. Feature #4 (BE passive) is the least common in informal, spoken English (see the BNC and COCA links), and it is even less common in the TV Corpus.
 

The charts show the normalized frequency (per million words) in the BNC and the last three decades of the TV Corpus. The features are also much more informal than COCA Spoken, which is not shown in the pictures below, but which can be seen from the COCA link.
