Consider the following data from Samoan: 

1. mate          ‘he dies’             mamate           ‘they die’
2. nofo          ‘he stays’             nonofo            ‘they stay’
3. galue         ‘he works’            galulue            ‘they work’    
4. tanu          ‘he buries’            tatanu              ‘they bury’
5. alofa         ‘he loves’             alolofa            ‘they love’
6. taʔoto        ‘he lies’              taʔoʔoto          ‘they lie’
7. atamaʔi     ‘he is intelligent’       atamamaʔi       ‘they are intelligent’

What morphological process is occurring? 

If ‘he is strong’ in Samoan is malosi, how would you say ‘they are strong’?
