Silver bearings in front - too much like Neptune (6)
I believe the answer is:
seagod
'neptune' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'silver bearings in front too much' is the wordplay.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'bearings' becomes 'se' (I can't justify this - if you can you should believe this answer much more).
'in front' says to put letters next to each other.
'too much' becomes 'od' (abbreviation for overdose).
'ag' put after 'se' is 'seag'.
'seag'+'od'='SEAGOD'
'like' is the link.
Can you help me to learn more?
(Another definition for seagod that I've seen is " marine commander".)
