I don't have much time, but here we go:
This refers to a specific permission in a specific context.
At the beginning for the Christian church in the 1st century, it was easier for Greeks and Romans to accept Jesus than it was for Jews, since Jews always have trouble accepting their own true prophets at first. For this reason, great signs and wonders were performed by Jesus, his 12 apostles and some of the early Christians, such as healing, speaking in tongues, etc. Those signs and wonders were temporary and that was their purpose, to witness to the Jews that their Messiah had come. At some churches in Greece, however, Ephesus, Corinth, etc., some false teachings were introduced into the church about speaking in tongues, that all Christians must speak in tongues as evidence of their conversion. These were perpetrated mostly by women for no particular reason. So Jews would walk into one of those churches, and all they heard was women chanting in weird tongues, at the same time, without interpreters...it was chaos.
1 Corinthians 14:22-23
Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers. 23So if the whole church comes together and everyone speaks in tongues, and some who do not understand[a] or some unbelievers come in, will they not say that you are out of your mind?
1 Corinthians 14:33-35
For God is not a God of disorder but of peace. As in all the congregations of the saints,
34 women should remain silent in the churches. They are not allowed to speak, but must be in submission, as the Law says.
35 If they want to inquire about something, they should ask their own husbands at home; for it is disgraceful for a woman to speak in the church.
So
1. Paul was putting a stop to that.
Also, because of their traditions, Jews would not allow a woman to teach them about God authoritatively. Therefore, at the beginning of the Christian church, it was important for Christian men to be the ones witnessing to Jews, in order to reach them and not turn them away.
So
2. Paul was telling Timothy not to permit women to witness to Jews or teach them authoritatively.
Signs and wonders have seized for now, Jews have loosened up, times have changed.
So STella, please teach us.
