In a latest report from wired, Google is said to ban 1400 offensive words to appear while you swipe also not suggested during autocomplete. Google bans words which will not be displayed while swiping letters or during auto complete. Google has a separate dictionary for offensive words which will block those words and would not be suggested for auto completion.
Some of the words which Google blocks are sex, panty, braless, uterus, intercourse. Some of the words related to undergarment and reproductive health Tampex, Lactation, preggers, panty, LSAT, pizzle, condom are some of the 1400 words you will not come across during typing.
But at the same time Google also gives an option to include those words and remove the blocking. This can be done from keyboard settings and then by disabling the “block offensive words” option.
Some of the Islamic words like Iftar and Sunni are also censored, but many other words related to Muslim religion are not banned and appear while swiping.
