The Japanese word for teacher is Sensei. The founder of Aikido, Mr Ueshiba, is known as O Sensei or great teacher.
On the mat, the instructor is referred to as Sensei.
At the beginning of class we bow to O Sensei, then bow to Sensei and say “o ne gai shi mas”, which means ‘please’ - in this context ‘please practice’. At the end of class we bow to O Sensei, then bow to Sensei and say “domo arigato gozaimashita” which is a very polite ‘thank you’ (generally, the longer a phrase is the more polite it is).
When practising with a partner we bow to each other before and after training together.
Bowing in the dojo is used to show respect to the memory of the founder of Aikido, to the instructor and to fellow Aikidoka (practitioners of Aikido). It is not to be construed as an act of worship.

Introduction to techniques
An Aikido technique is described by the attack, followed by the name of the technique. Sometimes it is specified whether the technique should be sitting or standing.
Most techniques have two forms, omote (positive, irimi) and ura (negative, tenkan).
When practising in pairs it is usual for one person to perform the technique four times (omote, right and left; ura, right and left), then the other person to perform the technique four times.
