I've noticed a couple of patterns in regards to forming nouns from verbs.
1) Removing the -ть from verbs ending in -бить/быть, -вить, чать and -ять and adding -тие (for example: разбить --> разбитие, закрыть --> закрытие). *However, I've noticed that there are some exceptions with suffix -ние (e.g. Обожать --> обожание).
2) removing -ть from -дать verbs (e.g. выдать --> выдача)
Can anyone help clear up the -ние / -тие distinction from the first question or help me work out simple formulas with remove verbal stems and adding suffixes? Also, if you also know any way of formulating adjectives from either verbs or nouns I'd also appreciate this.
Thanks!
